With the popularization of artificial intelligence, AI has penetrated into various industries. This paper introduces the principle of using the cutting-edge AI technology to realize telephone robot. Smart phone robot makes full use of artificial intelligence speech recognition technology and big data's accurate analysis and positioning, which is a subversive change to the traditional mode. is intelligent or the era of "artificial + intelligent voice" a way, smart phone robot is the gospel of the enterprise! Help enterprises to reduce costs, improve work efficiency, improve company performance!

The phone robot is more powerful than the manual seat is that the phone number is directly imported in the background, saving time and effort, and dialing automatically. Intelligent dialogue in turn, according to the system settings, customers can be screened and counted, and according to the degree of intelligent classification intention of customers, the Class A customers with the highest intention will be handed over to manual follow-up. In this way, the work efficiency of the whole e-commerce process can be greatly improved.

As a product of "artificial intelligence", it is gradually bringing great changes to the e-commerce industry, handing tedious, boring and time-consuming work to smart phone robots, background classified management, and elite sales follow-up. Not only greatly improve work efficiency, but also can better redistribute and regroup human resources to reduce enterprise operating costs! It should be something that every boss is thinking about.

For e-commerce companies, how to accurately identify real customers has been difficult to overcome. For smart phone robots, through human voice expert-level communication, we can simulate multiple rounds of interactive communication between e-marketing personnel and customers, accurately find users through user portraits and big data model, achieve accurate marketing, and quickly complete the screening and classification of ABCD customers.

Smart phone robot integrates many cutting-edge technologies such as Internet telephony, voice knowledge, natural voice understanding, multi-round dialogue, knowledge graph and so on into one intelligent product. It has become a leader in the industry and has brought gratifying changes to the outbound calling industry. It has been proved by many enterprises in just a few months that this is a good AI project to really increase revenue and reduce expenditure.

As an intelligent product today, intelligent phone robot can accurately respond to all kinds of questions raised by customers with human voice, thinking and tone intelligence in practical application. At the same time, its screening ability is also very strong, which can automatically classify the responding users according to the degree of intention, and help the manual agents to peel off the intended customers quickly.

It is the limit for employees to make 200,300 calls a day, but smart phone robots can make 800,300 effective calls a day, which increases efficiency several times, and higher efficiency means improved performance.

What is a phone robot?

Through ASR (speech recognition) and TTS (text to voice) to simulate the calls between real people and users, it can be used for business such as enterprise switchboard, automatic call, outbound marketing, questionnaire survey, etc., while supporting Baidu, HKUST, Aliyun and other ASR systems, real people can be pre-recorded, users are completely unaware of the robot.

How to develop a telephone robot

FreeSWITCH/Asterisk is a softswitch system, you can use the open source softswitch system to develop a VAD recording module, users start recording after speaking, stop talking, submit the recording to the speech recognition interface to convert the text, use semantic parsing interface (NPL) or simple keyword matching, return the pre-designed speech skills of the system, and convert TTS into voice (or human pre-recording) to play back to the user. Realize man-machine voice conversation.

Technical difficulties

When the robot speaks, the user starts to speak, and the robot has to deal with it in time, which is the so-called interruption, which can be solved by VAD algorithm and keyword interruption.

At present, it is difficult for robots to understand the meaning of users' words. At present, the main way is to design speech skills through keyword matching.

Support those ASR interfaces

Can support iFLYTEK, Baidu speech recognition, Aliyun speech recognition, Tencent speech recognition, Jettong Huasheng Lingyun and other SDK/API/MRCP interfaces.

How to use it

It can be docked with existing call centers, IPPBX,FreeSWITCH,Asterisk and other systems through SIP extension and SIP relay.

Smart ivr interface description

Smartivr is a Freeswitch-based telephone robot secondary development interface (restful), which supports docking with Asterisk.

User's guide

The user implements httpAPI by himself, and the robot program calls this interface, not the robot provides httpapi for the user to call.
