VAD configuration parameters.

Fields

sample_rate: u32

Sample rate in Hz.

frame_duration_ms: u32

Frame duration in milliseconds (typically 10–30ms).

start_threshold_db: f64

Energy threshold (dBFS) above noise floor to trigger speech start.

stop_threshold_db: f64

Energy threshold (dBFS) above noise floor to end speech.

min_speech_frames: u32

Minimum speech duration in frames before confirming speech.

hangover_frames: u32

Hangover duration in frames — keeps “speaking” state after energy drops.

speech_zcr_range: (f64, f64)

ZCR range for speech confirmation (low, high).

initial_noise_floor_db: f64

Initial noise floor estimate (dBFS).

pre_speech_frames: usize

Number of pre-speech frames to buffer.
