Speech Transforms and VAD

Use this sub-skill when the user needs audio enhancement, source separation, speech activity detection, realtime turn detection, or shared audio I/O and resampling guidance.

Route Here For

• Speech enhancement and source separation.
• VAD and diarization-style turn detection.
• Server-side server_vad planning.
• Audio I/O, resampling, normalization, trimming, and fixture validation.
• Safe command planning for mlx_audio.sts.generate and VAD probes.

Route Elsewhere

• For TTS generation or cloning, use ../tts-generation/.
• For transcription, alignment, or WER, use ../stt-transcription/.
• For server endpoints or conversion, use ../server-and-conversion/.

Fast Paths

• See references/audio-io-and-dsp.md for shared audio handling.
• See references/vad-and-realtime.md for turn detection and server-side VAD.
• See references/troubleshooting.md for audio, threshold, and dependency failures.
• Use scripts/validate_audio_io.py to confirm a tiny round trip.
• Use scripts/vad_turn_detection_probe.py to inspect synthetic VAD events.
• Use scripts/sts_command_builder.py to shape a safe enhancement command.
