Speech recognition

Speech Recognition can be activated / deactivated with the SPEECH_REC command.

When it is ON, notifications are sent when a “YES” or a “NO” is detected on the mic input. You can use theses notifications to trigger actions such as answering or rejecting a phone call.

Note that the Speech Recognition has a highest audio priority. It means that during a call or when music is streaming the audio won’t come out while the Speech Recognition is active.

Speech recognition requires a cVc license key.

Tone generation

Audio Agent allows for the playing of tones of any pitch with the TONE command. The parameters for the TONE command are detailed in Appendix B: Tones parameters and flags codes.
