Enable stream_ahead_of_real_time so assistant audio is sent to the client as soon as it is generated, and switch the input and output formats to pcm_24000 (the STS buffer's native rate) to avoid resampling. Bump the phonic dependency to 0.32.5 for the stream_ahead_of_real_time config field. Co-authored-by: Cursor <cursoragent@cursor.com>
Stamp each text chunk with the start/end time of the audio it is delivered alongside, tracked via a running audio cursor on the generation. This lets the transcript synchronizer align words by exact playback span instead of estimating from the speaking-rate detector. Co-authored-by: Cursor <cursoragent@cursor.com>
