This PR enables support for Voice Activity Detection (VAD) in the Go bindings for whisper.cpp. It adds parameters and setter methods in the Go API so that users can enable and configure VAD when using whisper through Go.
Specifically:
Introduces new Params fields for VAD configuration (e.g. vad, vad_model_path, vad_threshold, vad_min_speech_ms, vad_min_silence_ms, vad_max_speech_sec, vad_speech_pad_ms, vad_samples_overlap).
GitHub
Exposes corresponding
SetVAD,SetVADModelPath,SetVADThreshold, etc., methods on the high-level Go Context interface for easy use in Go code.GitHub
Maintains full backward compatibility: existing Go code that does not call these new methods should continue working as before, without any change.
With this change, Go users of whisper.cpp can now leverage VAD to automatically skip silence / non-speech regions, which can reduce processing time and improve the quality of segment boundaries (for example avoiding segmentation in silence).
