This article is about how to carry out DJI and GoPro motion camera voice control comparison and voice control technology as well as innovative applications, the editor feels very practical, so share with you to learn, I hope you can get something after reading this article, say no more, follow the editor to have a look.

As a motion camera, it must satisfy the hands-free operation of HANDS-FREE in the motion scene, while voice gives users an intuitive, powerful and natural way of human-computer interaction in the most natural way.

GoPro-

GoPro uses Sensory's offline multilingual speech recognition and control technology, which can activate and wake up Always-on/Always-listening keyword devices, as well as up to several offline voice commands.

The following GoPro products support offline voice control-

HERO8 Black

HERO7 (White, Silver, & Black)

HERO6 Black

Fusion

HERO5 Black

HERO5 Session

HERO (2018)

Remo

Offline voice control with the following multiple voice messages is supported-

English (and Australian., U.K.)

French

German

Italian

Portuguese**

Russian**

Spanish

Chinese

Korean**

Japanese

* * Voice control is not available for these languages with Remo.

Up to 12 offline voice controls are supported, including the wake-up word "Go Pro"

"GoPro Start Recording"

GoPro HiLight (Adds a highlight tag while recording video)

"GoPro Stop Recording"

"GoPro Take a Photo"

"GoPro Shoot Burst"

"GoPro Start Time Lapse"

"GoPro Stop Time Lapse"

"GoPro Video Mode"

"GoPro Photo Mode"

"GoPro Time Lapse Mode"

"GoPro Burst Mode"

"GoPro Turn Off"

And in the following models, the device that supports low-power real-time monitoring of voice commands is powered on through "GoPro Turn On".

"GoPro Turn On" (only with HERO7 Black, HERO6 Black, & Remo + HERO5 Black)

In addition, GoPro also supports two "secret" voice commands, namely "That was sick" and "Oh Shit", to achieve the same function as "GoPro Hilight", but through more colloquial expression, it gets rid of seriousness and enhances the interest of voice interaction.

Now let's take a look at the DJI OSMO motion camera-

DJI OSMO motion camera also supports voice control, but compared with GoPro motion camera, its voice function and supported languages are as follows-

Only Chinese and English languages are supported-

English voice command-

Take photoScreen switchstart recordingstop recordingshut down

Chinese voice commands-

Take a picture, switch the screen, start recording, stop recording, turn off the camera.

The voice boot of the device is not supported, and there are few supported languages and voice commands, and the lack of pre-awakening words will affect the accuracy of voice command recognition to a certain extent and affect the user experience.

Voice print recognition and user-defined voice commands

Standardized voice commands, such as "start recording", may be mistakenly triggered by other users, and can also be recognized and triggered by the device when other users say "start recording". The user input voice command (Fixed-Phrase), which combines the user's voiceprint characteristics, and even the user-defined voice command (Text-Dependent), not only solves the false trigger, but also enhances the interest, for example, the user can use "sesame open door" as the voice command to take a photo and trigger the camera to take a picture.

Sound event recognition (Sound Event Recognition) triggers automatic recognition and response of motion cameras-

Then let's explore more possibilities of voice interaction in the control of motion cameras. In addition to using voice commands, we can set the task to be triggered by the recognition of a specific sound event (Sound Event Recognition).

For example, motorcycle enthusiasts can record the sound of the motorcycle engine in advance, and the Sensory SoundID sound event recognition engine will extract sound features as sound events "Motocycle engine start". The motorcyclist starts the motorcycle, and the motion camera automatically recognizes the sound of the motorcycle engine, and starts shooting spontaneously.

Or when taking a selfie, you can record "Hand Clapping 3 times" three times in a row as a sound event, so that you can start shooting photos or videos by clapping your hands three times in a row.

The development of embedded voice technology brings richer experience and more possibilities for the interaction between people and devices. The practice of device-side voice interaction between GoPro and DJI on wearable motion cameras has greatly improved the user experience. But this is not perfect, there is still a lot of room for performance and user experience improvement. Speaker Identification voiceprint user identification technology, ASR voice recognition technology, and Sound Event Detection voice event recognition technology provide a more solid technical foundation for user Hands-free interaction experience, and open up an imaginative application space. The above is how to compare the voice control and voice control technology of DJI and GoPro motion cameras as well as innovative applications. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article.
