Implementations

impl VoiceActivityDetector

pub fn new(config: VadConfig) -> VoiceActivityDetector

Create a new VAD with the given configuration.

pub fn state(&self) -> VadState

Current VAD state.

pub fn is_speaking(&self) -> bool

Whether speech is currently detected (Speech or Hangover state).

pub fn noise_floor_db(&self) -> f64

Current noise floor estimate (dBFS).

pub fn is_wavekat_backed(&self) -> bool

Whether this detector is currently using the WaveKat backend.

pub fn backend_name(&self) -> &'static str

Name of the active backend.

pub fn last_probability(&self) -> Option<f32>

Last normalized speech probability or binary backend decision.

pub fn drain_pre_speech(&mut self) -> Vec<Vec<i16>>

Get pre-speech frames (the frames captured just before speech onset).

pub fn process_frame(&mut self, samples: &[i16]) -> Option<VadEvent>

Process a single audio frame and return any state-change event.

pub fn reset(&mut self)

Reset the VAD to its initial state.
