Introduction to the beginning

Since the beginning of 2023, we have been amazed by the explosion of technology in the field of AI, in which the strong creativity of AIGC (generative artificial intelligence) has been quickly applied to a variety of industries, including education. AI learning machine is a typical application in the field of model landing education.

Just as the Singles' Day Shopping Festival is coming, AI learning machines on the market have also been greatly promoted, making many parents dazzling. But AI this selling point does not have a clear standard, a little bit of artificial intelligence technology dare to call themselves "AI learning machine". How to choose a learning machine that can really give full play to the potential of the AI model? This ten thousand word long article shopping guide takes you to choose the AI learning machine hand in hand.

The so-called AI learning machine is a new learning machine that uses artificial intelligence technology to assist children's learning. it can provide personalized teaching content and interactive ways according to children's learning situation and interests, so that children can learn knowledge, improve performance and cultivate interest in a relaxed and happy atmosphere.

And thanks to the rapid development of AI large model technology in recent months, the AI learning machines of some leading enterprises in the market have upgraded AI large model technology. In this paper, CTOnews.com chooses two representative AI learning machines and one traditional learning machine that focuses on curriculum resources. They are iFLYTEK AI learning machine T20 Pro, small intelligent learning tablet Z20 and learning thinking learning machine XPad.

The iFLYTEK AI learning machine T20 Pro carries the iFLYTEK Spark model, which has been named the "smartest big model" by the MIT Technology Review. The Z20, a small intelligent learning tablet, carries Baidu's big model of Wenxin word, which was released earlier than iFLYTEK, but the learning machine was carried later than iFLYTEK. The learning and thinking learning machine XPad has not yet been equipped with a large model.

▲ photo source "MIT Technology Review" below to take a look at the AI era who can better give full play to the potential of the AI model for children's learning services, who is more suitable for contemporary children's needs of auxiliary learning tools. I hope it can help you in the purchase of Singles Day holiday.

Refuse to do exercises, refuse to brush lessons, personalized precision learning is the learning machine AI ability touchstone we mentioned at the beginning, now AI learning machine for AI this selling point does not have a clear standard, a little bit of artificial intelligence technology dare to call themselves "AI learning machine". Since Xunfei released the "AI Precision" function in 2019, major brands are following up, and some traditional brands are no exception, so AI Precision can be said to be the touchstone of AI ability.

So in the following evaluation, the author will focus on the performance of AI precision learning functions of various manufacturers (covering subjects, localization, covering questions, recommended accuracy) to see how far the AI capabilities of these learning machines have gone.

Subjects covered: iFLYTEK's Precision Learning system is the first personalized precision learning system released in the industry, which supports key subjects of mathematics, English, physics, chemistry and biology from primary school to senior high school. IFLYTEK AI learning machine integrates big data with 10 billion-level education into the knowledge graph, so its knowledge graph covers the most complete and detailed, and it is also the only knowledge point in the three products that has a clear logical relationship.

▲ iFLYTEK T20 Pro covers Chinese, math, English, Taoism, history, geography, science, biology, chemistry and other subjects from primary to senior high school, as well as a wide range of subjects. However, the disassembly of knowledge points is not as detailed as iFLYTEK, and there is no logical relationship between knowledge points directly. This set of learning is more like learning according to a specific set of algorithms, and does not give full play to the proud AI technology, which still has a lot of room for improvement.

▲ Z20 Plus study while thinking about XPad's AI precision learning only supports primary school mathematics, compared with iFLYTEK and Xiaodu, they lack a lot in terms of school section and subject coverage.

▲ XPad question coverage: the iFLYTEK T20 Pro is also equipped with a standard AI stylus to support answering on a full-question machine. Compared with simply answering multiple-choice and judging questions, this handwritten answer is more intuitive and more conducive to children's preparation for the exam. In particular, it supports direct answer and diagnosis on high-score machines such as application questions and solution questions, which can completely cover all types of questions in the school examination and realize accurate diagnosis based on problem-solving steps.

▲ iFLYTEK T20 Pro and Xiaodu and Xue Ersi are not equipped with a stylus, only support objective questions to answer directly on the computer.

Because there is no stylus in ▲ Z20 Plus, both of them naturally can not support the computer answer and diagnosis of high-score big questions such as application questions and solving problems.

▲ learning and thinking about XPad localization test site coverage: localization is particularly important for children of junior high school age. Take junior high school mathematics as an example, there are 13 versions of junior high school mathematics textbooks in the whole country, and the versions of teaching materials are different in different places, which results in different examination focuses in different places. For example, a knowledge point is a regular test point in Beijing, but it may not be tested at all in Jiangsu; another example is that a knowledge point is very difficult to examine in Hubei, often taking big questions, but may only take simple multiple-choice questions in Guangdong.

Therefore, when parents choose auxiliary teaching materials for their children, they should not blindly trust the secret books of famous schools across the country. Local real problems in previous years may be even more helpful. Localization is to help children pertinently practice local knowledge points and improve their exam-taking ability.

IFLYTEK AI learning machine is the only one of the three learning machines to achieve localization. According to the analysis of localized education big data, it understands the differences in examination priorities in different regions, and gives priority to recommending local knowledge points of high-frequency inspection to students to improve the pertinence of learning.

▲ iFLYTEK T20 Pro while in other home products, the author did not find the characteristics of local test site coverage, the same knowledge points all use similar questions.

Recommendation accuracy: AI Precision Learning generally uses several questions to test children's weaknesses, and then accurately recommends the product logic of relevant knowledge points and topic exercises, so the accuracy of recommendation directly affects the effect of children's learning and the efficiency of improvement.

The author here uses iFLYTEK T20 Pro to do an after-class practice of second-grade math problems. after finishing a set of questions, iFLYTEK AI will give scores and provide a diagnostic report.

▲ iFLYTEK T20 Pro then, iFLYTEK T20 Pro will give the knowledge points related to the error problem and the method of solving the problem, and then click on the precise exercise in the lower right corner, it will push the child several similar questions for consolidation exercises. There is no doubt that such a learning method is very scientific. IFLYTEK AI Learning Machine through the analysis of this year's high school entrance examination papers, found that the proportion of test sites recommended by the learning machine reached 94.8%, of which 87.7% were given the first priority.

At the same time, iFLYTEK also pays attention to the quality of recommended questions, ensures the quality and accuracy of recommended questions through multi-dimensional comparison, and gives priority to recommending weak points of knowledge that children will not know and knowledge points that are often tested locally.

Help children improve accurately and efficiently through the complete logic of "diagnosis-learning-practice".

▲ iFLYTEK T20 Pro as a contrast, the small intelligent learning tablet Z20 has only a simple analysis after the end of the answer, no detailed interpretation report, and no problem-solving method by analogy. Wrong questions can be added to the wrong problem book, but there is no targeted localization topic push.

The analysis of ▲ Z20 Plus learning and thinking XPad is more simple, and it does not provide the function of wrong questions. It is only a simple answer tool, which is insufficient in helping children to understand wrong questions.

▲ think about XPad when time and attention have become the most precious things for children, "doing exercises" can no longer meet the current learning needs of children. How to use AI to help children learn the knowledge they need more efficiently, the biggest difficulty lies in how to solve the problem of personalization.

Children need to face different examination contents in different regions, what to learn is different; each child's mastery of knowledge points is also different, two children who both get 70 points may have completely different weak points. And the learning ability of each child to the knowledge point is also different, the same problem is wrong, 90 points of the child may just be careless, only a little study can be fully mastered, but the test 75 points of the child may be the pioneer knowledge points did not learn well, only according to clues to find the first to learn the pioneer knowledge points, and then learn the knowledge points, so that we can really master the knowledge points.

Because every child is different, "personalization" is particularly important.

IFLYTEK AI learning machine has obvious advantages in subject coverage, localized test site coverage, comprehensive and accurate recommendation of questions, and so on. With the support of AI technology, it can provide students with personalized learning content and guidance. At the same time, the iFLYTEK AI learning machine has also been jointly verified by a number of university expert research groups, which proves its reliability and effectiveness in improving the learning effect. With the continuous development of artificial intelligence technology, iFLYTEK AI learning machine will further improve the efficiency and accuracy of learning.

Small intelligent learning tablet Z20 Plus and learning and thinking learning machine XPad do have accurate learning function, but the AI ability is insufficient, and it lags behind iFLYTEK in personalization and learning closed loop, so the effect is poor. The reasons for the gap are different: Xiao du is a technology-based Internet company, limited by the accumulation of big data in education, the accuracy of the knowledge graph and localization is difficult to catch up with iFLYTEK in the short term; learning and thinking about deep education for many years, but AI is not its advantage, so the development of "AI precision learning" function is not sufficient.

Large model empowering composition correction: the deeper the analysis, the better, the more targeted, the better for children's Chinese learning, the cultivation of composition ability is the most important part. So in the past two years, AI learners tend to make efforts in the field of composition tutoring. In fact, AI composition correction is a technically difficult task. Children's words are often relatively immature, AI recognition is not small, language errors also need AI comprehension ability to be strong enough. Of the three learning machines we evaluated today, the iFLYTEK AI T20 Pro can use a flip camera for upside-down shooting, making it clear and easy to use.

▲ iFLYTEK T20 Pro small Z20 Plus also has the function of AI composition assistant. But in the scanning process, because the small Z20 Plus does not flip the camera design, so must rely on the "smart eye", in fact, is a well-designed angle mirror, in order to achieve overshoot.

▲ small Z20 Plus camera can only correct math problems and look up words, does not provide AI composition correction function, the author has not found other composition correction entry.

▲ learning and thinking XPad correction dimensions and results: iFLYTEK's spark cognitive model can guide the rhetoric, expression and emotion of the writing like a human teacher, and give suggestions and model essays for revision. First of all, the composition correction function of iFLYTEK AI learning machine T20 Pro is divided into three stages: basic correction, advanced correction and promotion suggestions. In the basic correction stage, it can correct wrong words, wrong words, punctuation, pinyin, broken sentences and language defects, and analyze the causes of errors. From our recognition results, the recognition rate of iFLYTEK AI is quite high, and the speed of AI progress is amazing. Also achieved a deep understanding of the content and suggestions, really like the teacher to give comments and amendments.

▲ iFLYTEK T20 Pro

▲ iFLYTEK T20 Pro small Z20 Plus detailed correction interface is quite clear, it recognizes all the text and accurately finds the typos in it. However, some of the altered symbols used by children cannot be identified. Correction is a little more mechanical, lack of human teachers like the exchange of flu.

▲ small Z20 Plus Writing suggestion: in the writing suggestion stage, iFLYTEK can analyze the layout of the whole article, deeply understand the meaning, central idea and specific content of the topic, and make humanoid corrections on language logic, emotional expression and writing style. In the promotion suggestion stage, it can summarize the problems and give writing suggestions and optimization references.

▲ iFLYTEK T20 Pro A small AI based on Wen Xin's words will directly give the child a set of scores and suggestions, supplemented by radar maps. However, the author thinks that this correction suggestion is a bit of empty talk. I feel that it is established in any article, and the pertinence is not strong.

▲ small Z20 Plus model article material: finally, the iFLYTEK AI learning machine T20 Pro will also provide children with several sets of excellent model essays and tell them where they are good, instead of letting them imitate them mechanically. There are also some good words and sentences below, which are easy to learn and use in the next composition. It can be said that the whole composition correction process of iFLYTEK AI learning machine T20 Pro is quite smooth and efficient.

▲ iFLYTEK T20 Pro

▲ iFLYTEK T20 Pro Xiaodu also provides modification suggestions and embellishments, but it does not provide a reference for sample articles and good words and sentences, and has less information than the iFLYTEK AI learning machine T20 Pro.

▲ small Z20 Plus generally speaking, iFLYTEK T20 Pro and small Z20 Plus both have AI composition correction function. But the T20 Pro, which is blessed by the spark cognitive model, performs better in the evaluation. It can comprehensively analyze and evaluate the structure, content and language of the composition, help children find problems and provide suggestions for improvement. Through the connection with learning cards and massive model essays, and to guide the rhetoric, expression and emotion of the writing like a human teacher, it shows obvious advantages compared with the relatively simple Z20 Plus and the learning and thinking XPad with no related functions at all.

Large model enabling oral practice: simulating real auxiliary learning scenarios is very important for English learning to "open your mouth". As long as you listen more and speak more, the language can be mastered naturally. Therefore, the major learning machine manufacturers also pay great attention to oral practice. However, only iFLYTEK and Xiaodu, two companies with the ability to model the big language of AI, can combine AI with oral practice to achieve natural man-machine dialogue, rather than following it as rigidly as traditional learning machines.

When we open the iFLYTEK T20 Pro oral standard practice, we can see three options, namely, phonetic alphabet learning, oral practice and Talk Talk. The first two functions are relatively regular, and the third Talk Talk is the real AI cool techs.

▲ iFLYTEK T20 Pro after opening the oral exercise, we can first choose a topic, and then start a dialogue with "AI partner Lucy". After all, dialogue can be in English, and so can Chinese. Avoid the situation that your child's English is stuck and frustrated and don't want to practice any more.

▲ iFLYTEK T20 Pro Xiaodu also provides AI dialogue practice function based on the big model of Wen Xin Yi Yan. You can also choose a topic and carry out exercises.

▲ small Z20 Plus oral practice is a project that relies on AI, and learning and thinking still has no advantage in this field. Learning and thinking XPad does not offer AI oral practice programs in primary and secondary schools, but only provides Harvard foreign teacher enlightenment courses for preschool children under the enlightenment system. And the proportion of AI intervention is not as obvious as iFLYTEK and Xiaodu.

The process of ▲ learning and thinking XPad iFLYTEK T20 Pro speaking exercise is very similar to the feeling of real-life conversation. The content of the dialogue can be translated two-way with one button, the child speaks Chinese, and the learning machine can understand and maintain a smooth conversation; according to the understanding of the context, the production content can be logically related, and multiple rounds of dialogue can be conducted; children are free to choose the difficulty, speed and style of the dialogue; the dialogue process can not only evaluate pronunciation, but also detect grammar synchronous learning.

▲ iFLYTEK T20 Pro's entire dialogue interface is similar to iFLYTEK, but the pronunciation of AI lacks a sense of substitution. And in the course of practice, you can only speak English, and speaking Chinese will only prompt you how to say it in English, but there is no further dialogue. If it gets stuck, it is difficult to further study and correct it. It can be said that there is room for further development of the AI ability of Wen Xin.

▲ small Z20 Plus

▲ small Z20 Plus from the above AI oral practice comparison, iFLYTEK in the AI language model enabling learning machine ahead of the industry, not only the first to put forward the concept of AI precision, and in the era of the AIGC explosion in 2023 quickly applied this technology to the learning machine, and finally manifested as a very natural virtual human bilingual dialogue. It can be said that the performance of iFLYTEK in the AI big language model is already the first echelon in the learning machine market.

The big model brings more extensibility to parent-child education and knowledge learning, of course, the big model is not limited to the basic learning contents such as routine composition correction and oral practice. For example, iFLYTEK T20 Pro applies the big model to parent-child communication education. Most people are first-time parents and do not have rich parenting experience. In the scientific education of children and the correct guidance and correction of children's problems, the advice that the big model can give must be more reliable than the experience shared by relatives and friends, so the parent-child assistant based on the big model is integrated into iFLYTEK's iFLYTEK AI learning App. It can help parents to cultivate their children's behavior habits, parent-child communication, parent-child interaction and so on. For example, if my child is addicted to short videos, the parent-child assistant will give seven effective suggestions such as setting the length of time to watch and stimulating other interests, which will undoubtedly make parents take a lot of detours in educating their children.

▲ iFLYTEK AI to learn "parent-child assistant" iFLYTEK T20 Pro programming function is another unique bright spot, with the great-leap-forward development of artificial intelligence, information technology has been written into the new curriculum requirements, more and more parents want to take advantage of their children to cultivate some programming thinking. Therefore, iFLYTEK T20 Pro has built-in rich programming resources, including programming materials, programming question bank and programming projects. Through these resources, students can systematically study and practice programming, and improve their programming ability and creativity.

▲ iFLYTEK T20 Pro iFLYTEK T20 Pro is also based on Spark Model technology, equipped with AI programming assistant, through artificial intelligence technology to provide personalized programming learning recommendations and guidance. It can intelligently recommend suitable learning content and learning path according to students' learning situation and ability level, and help students better master programming knowledge and skills. Support a variety of programming languages, including Python, Java, C++ and so on. Students can choose the appropriate programming language to learn and practice according to their own interests and needs.

It is worth mentioning that iFLYTEK T20 Pro can also provide a real-time programming environment, where students can carry out programming practice and debugging on the learning machine, view the running results of the code in real time, and improve the efficiency and accuracy of programming.

Of course, the questions and answers that the big model is best at can also be found in the iFLYTEK learning machine, which supports its own question and answer, whether you ask it "what is a black hole" or "what does it mean that a small boat has sailed over ten thousand mountains"? it can answer accurately.

▲ iFLYTEK T20 Pro small intelligent learning tablet Z20 has a relatively simple application to other functions of the large model, mainly integrating the Wen Xin big model directly into the voice assistant, and named it Xiaodu Qinghe speech learning assistant. With the large model empowerment, the small intelligent learning tablet Z20 can also provide relatively accurate and comprehensive answers to complex problems, such as my question: "where is the good memory of Yueyang Tower?" Xiao du will analyze the solution from many angles, such as writing style, thought and so on.

▲ small intelligent learning tablet Z20 and, because Xiaodu Qinghe is a learning assistant for minors, some discordant content will also be blocked, the author intentionally fishing, Xiaodu can be very smart to "play dumb".

▲ small intelligent learning tablet Z20 learning and thinking learning machine XPad does not have the educational function of more model blessing, its built-in literacy education content is relatively simple and young, there are four categories of history and culture, popular science encyclopedia, four masterpieces, sound and body aesthetic education, but the number of each category is small, such as sound and body aesthetic education, only 13 interest courses.

▲ XPad generally speaking, the parent-child assistants of iFLYTEK T20 Pro can provide parents with a more scientific and reasonable parenting style through the Spark Model. Programming function can also help children improve their programming ability and creativity by providing personalized learning recommendations and guidance, rich programming resources and real-time programming environment. Xiaodu Qinghe voice learning assistant of Xiaodu intelligent learning tablet Z20 can answer some complex and abstract questions for children, and the content is relatively green and healthy. Learning and thinking learning machine XPad lacks other applications of large models, and its intelligent performance is much lower than that of the other two learning machines.

Choose learning resources, regardless of quantity, many parents will fall into the misunderstanding of resources when buying learning machines, thinking that the more resources the better, which is like adults buying books but not reading them. Now what children lack most is time, too many resources children really do not have time to digest them one by one. In this era of resource explosion, access to resources has become easy, so we think that parents should "exercise restraint" when purchasing learning materials for their children and choose what is best for their children.

As the only brand developed from online courses among the three competitors, Learning and thinking naturally has a certain advantage in terms of the number of learning resources. Learning and thinking XPad is an intelligent learning machine that integrates learning resources, self-research and excellent courses and intelligent tutoring. XPad's learning resources cover the period from early childhood to junior high school. It provides a wealth of teaching materials, teaching aids and online course resources to help students systematically learn the knowledge of various disciplines.

The biggest competitiveness of ▲ while thinking about XPad and thinking about XPad is naturally the excellent courses of self-study, which is a kind of video courses that are more difficult and explain in detail. These courses are suitable for middle-and high-level students who want to move forward, and can help them improve their learning level and expand their knowledge, which is slightly different from those offered by Xiaodu and iFLYTEK.

▲ think about XPad for younger children, XPad provides RAZ's English enlightenment cartoons. But there is no corresponding textbook. It can be said that Learning and thinking has given full play to their advantages in video courses, but it is not as small as iFLYTEK and small in terms of picture and text resources.

▲ learning and thinking XPad iFLYTEK T20 Pro in these three learning machines is not the most resources, taking the route of high-quality resources. One is to introduce international authoritative resources, such as Oxford University Press authorized picture books, and the other is to cooperate with domestic authorities to develop their own content, such as Ryan Bear AI English and iFLYTEK wonderful dynamic picture book resources with East China normal University and Shanghai Foreign Studies University, which deeply integrates English learning with children's cognitive psychology and AI technology. Third, the resources accumulated by deep ploughing education over the past 19 years, such as iFLYTEK Book City, secret volume resources of 50, 000 primary and secondary schools across the country, and so on.

▲ iFLYTEK T20 Pro small Z20 Plus (Gao Si Edition), as its name implies, is a learning machine that introduces Gao Si courses as an advantage resource. So its biggest advantage is naturally Gao Si class. The Gao Si curriculum covers preschool, primary and junior high school stages, provides children with systematic learning content, and is famous for its rich teaching experience and high-quality teaching materials, which can help children establish a solid learning foundation.

▲ small Z20 Plus Gao Si course covers math, English, Chinese, physics, chemistry and other major disciplines, taking into account both thinking and comprehensive quality training. It is currently a set of courses widely recognized by the industry, and it is also the biggest competitiveness of the small Z20 Plus (Goss version). Xiaodu also uses AI technology to provide children with intelligent interaction, intelligent evaluation, intelligent recommendation and other functions. Provide personalized Gao Si courses according to your child's learning situation and preferences.

▲ small Z20 Plus course adopts the mode of video class, and the quality of the lecture is very high. The only pity is that it only offers courses in the voluntary trading phase, and there are no resources in high school.

▲ small Z20 Plus to sum up, each learning machine has its own unique advantages and characteristics. Learning and thinking XPad provides more in-depth self-training courses, iFLYTEK AI learning machine T20 Pro resources are small, but the victory lies in the quality, the small Z20 Plus (Gao Si version) introduced the Gauss course as an advantage resource. Parents can choose a suitable learning machine according to their children's learning stage and interests.

High-configuration hardware is very important for children's experience and continuous upgrade of functions. As a CTOnews.com, we certainly need to pay attention to the hardware performance of these learning machines. Admittedly, learning machines are very different from traditional tablets, and what consumers value most when buying is not their powerful performance and bright screens.

However, considering that the purchase cost of the learning machine is not low, it is a durable product, and the learning cost for children is high, we still suggest that parents try to choose a high configuration when buying a learning machine. And with the continuous development of science and technology, various companies are constantly updating resources through software push. A ceiling-level hardware brings not only the current experience, but also the possibility of unlimited software function upgrades in the future.

In terms of performance, the author has an intuitive experience that the iFLYTEK T20 Pro is very smooth to use and is almost the same as our daily mobile tablet. On the other hand, the small intelligent learning tablet Z20 Plus and the learning and thinking machine XPad are relatively less smooth and often have some subtle stutters.

In terms of storage capacity of ▲ iFLYTEK T20 Pro, the memory configuration of iFLYTEK T20 Pro is 8 million 512G, the memory configuration of small Z20 Plus is 6 million 256G, and that of learning and thinking XPad is only 6 million 128g. In terms of durability, the iFLYTEK T20 Pro is undoubtedly better.

▲ iFLYTEK T20 Pro in terms of camera configuration, the three learning machines have a very obvious gap. The iFLYTEK T20 Pro uses a 5000-megapixel ultra-wide-angle camera that no other home has, and uses an electric reversal design, as well as a rear camera and an overhead camera.

The ▲ iFLYTEK T20 Pro small Z20 Plus has a 5-megapixel rear camera and an 8-megapixel front camera. But because there is no flipping function, the task that wants to overlook the desktop must be done through a refractor.

▲ small Z20 Plus learning XPad has a front and a rear, the top shot also needs to be equipped with a refractor, but also put it on a high bracket, which is relatively inconvenient to operate.

▲ think about XPad in addition to the tablet itself, the iFLYTEK T20 Pro comes with a unique accessory: the AI stylus. Support 4096 level of pressure, you can answer the whole question directly on the screen. From then on, children do not have to work hard to print out after-class exercises, which other learning machines do not have.

▲ iFLYTEK T20 Pro screen eye protection is the biggest need, care of children's vision health screen is also worth talking about. These three learning machines all use non-reflective eye protection screen to effectively reduce eye fatigue, which is a great progress in the industry. In terms of specific parameters, the iFLYTEK T20 Pro screen size of 13.3in, the resolution of 2560x1600, that is, 2.5K, support 90Hz refresh rate, and passed the national eye care professional test, Rheinland TUV no strobe certification and Rheinland TUV hardware-level low Blu-ray certification and other certification, is a big screen with good eye protection.

The ▲ iFLYTEK T20 Pro small intelligent learning tablet Z20 Plus also has a screen size of 13.3 inches, but only has a resolution of 1920x1080 and only supports 60Hz refresh rate. So the degree of fineness is much worse than that of iFLYTEK T20 Pro. In terms of eye protection, the small Z20 Plus has indeed made efforts, it has 15 eye protection functions, coupled with the German Rheinland double certification, the overall feeling is more comfortable.

▲ small intelligent learning tablet Z20 Plus learning machine XPad is the smallest, and the fine degree of the screen is relatively high. It is equipped with an 11-inch IPS paper screen with a resolution of 2176 to 1600, or 2K. However, the author feels that its overall color is green in the process of use, and there is room for further improvement in color correction.

▲ learning machine XPad from the above introduction, we can see that the screens of these three learning machines have certain eye protection functions, but the iFLYTEK T20 Pro has the largest screen size and the highest resolution, can show more content and details, suitable for online classes, videos and other multimedia learning methods, and supports 90Hz refresh rate, smoother than the other two 60Hz, can reduce the phenomenon of drag and stutter. Is the best comprehensive look and feel of a product.

▲ iFLYTEK T20 Pro in addition, the iFLYTEK T20 Pro is also equipped with a sitting posture detection camera and a TOF real-time distance sensor, which can detect the child's sitting posture in real time.

▲ iFLYTEK T20 Pro can detect 10 items, such as side face, lying table, hands supporting face, lowering head, tilting head, hunchback, body tilt, too close to the screen, etc., but also provides sitting posture detection of paper books and learning machines in two learning scenes with very meticulous functions. You can also detect the brightness and color temperature of the ambient light in real time, and then give adjustment suggestions, for example, when it detects dim light, it will remind the child to slightly brighten the screen, and when the volume is detected to be too loud, it will remind the child to turn down the volume. From sitting posture to using eyes, iFLYTEK T20 Pro can protect children's health in all aspects.

▲ small Z20 Plus small Z20 Plus also has a 2-megapixel sitting posture detection camera, which can monitor the child's eye use and remind the child to rest as soon as possible. Learning while thinking has no related function.

From the hardware comparison and health guard comparison above, iFLYTEK T20 Pro is the overall leader. It is full of material on screen, performance, memory and camera hardware. And use these hardware to provide omni-directional sitting posture guard and vision and hearing guard. The small Z20 Plus ranks second in hardware, with sitting posture reminders and eye protection, but with low screen resolution and no hearing protection. Learning and thinking XPad lacks the above functions.

Summary from the above test results, it is not difficult to see that each of the three devices has its own focus. Generally speaking, the comprehensive quality of iFLYTEK AI learning machine T20Pro is obviously stronger. IFLYTEK AI learning machine T20Pro is in the lead in both hardware and software. A high hardware configuration means that you can spend more time with your child throughout his K12 learning career. In the aspect of software, with the blessing of the spark cognitive model, the learning guidance is more detailed, the topic recommendation is more targeted, the homework correction is more accurate and has reference value, and the parents' auxiliary learning is also more worry-free.

The advantage of small Z20 Plus is the large modeling ability brought by Wen Xin, which other countries do not have, but the development degree and enabling effect of AI technology is not as good as that of iFLYTEK AI learning machine T20Pro. At present, the mainstream AI functions in the market are all equipped with small Z20 Plus, but they need to be further developed. The Gao Si course, which is exclusive to the small Z20 Plus, is also attractive to parents who value this resource, but it should be noted that there are some barriers to use and not all children are suitable for it.

The advantage of learning while thinking about XPad is the learning resources that have been ploughed for many years. As an enterprise that started education, it has certain advantages in online courses, teaching materials, teaching aids and other resources. However, compared with the other two technology companies, their hardware products themselves are lacklustre, and because they do not have their own AI language model, new functions such as composition correction and oral follow-up reading are also lacking. The author believes that AI learning machine is more suitable for children's learning needs at present and in the future, and all learning machine manufacturers should speed up the exploration of AI technology.

Finally, the author would like to say that the AI learning machine is a new product and a learning tool that can better adapt to the development of the times and the needs of family learning. Nowadays, watching traditional online courses and making paper-based teaching aids have become a thing of the past. It coincides with the beginning of the school season, parents should choose what is most suitable for their children, do not blindly believe in brand marketing, it depends on the feedback and effect of real users, as well as whether there is an authoritative endorsement. AI precision is the touchstone of learning machine AI ability. Before buying, we should pay attention to the performance of learning machine in this function. Coinciding with the Singles Day holiday, parents also need to pay attention to the durability of the learning machine, whether the hardware is smooth and whether the software can be continuously upgraded before buying. Learning machine is a long-term investment for children. Only by choosing a product that is easy to use, durable and stands in the future is a product that is really suitable for children's growth.
