Technical Summary
Contutor AI Real-time Translator · Voice Pipeline
How It Works (Overview)
When the device screen is on, it supports o
ffl
ine wake-word activation. After wake-up, voice is captured, processed with
echo cancellation, encoded with Opus, and transmitted to the Contutor app via BLE. The app or cloud service then
performs recognition and translation generation, and sends the response back (such as audio) for playback on the
device.
App-side Capabilities Required
Establish BLE connection with the device, and receive status updates plus Opus audio streams.
Decode or forward audio data, then complete speech recognition and large-model requests.
Return AI translation output to the device for playback.
