Struct BargeInDetector 

pub struct BargeInDetector { /* private fields */ }

Barge-in detector — checks whether user speech should interrupt model output.

Implementations

impl BargeInDetector

pub fn new(config: BargeInConfig) -> Self

Create a new barge-in detector.

pub fn check( &mut self, current_phase: SessionPhase, vad_is_speaking: bool, ) -> BargeInAction

Check whether a VAD speech detection during model output should trigger barge-in.

Call this when the VAD detects speech while the session is in ModelSpeaking phase.

When tentative mode is enabled, the sequence is:

• First speech frame → Duck(volume) (reduce playback volume)
• Sustained speech reaching min_speech_frames → Interrupt (flush and signal)
• Silence before confirmation → Restore (false positive)

When tentative mode is disabled, the legacy behavior applies:

• None until min_speech_frames consecutive frames → Interrupt

pub fn reset(&mut self)

Reset the detector state.

pub fn execute_barge_in(jitter_buffer: &mut AudioJitterBuffer) -> SessionCommand

Execute the barge-in sequence:

1. Flush the jitter buffer (instant silence)
2. Return the command to signal activity start

The caller is responsible for sending the command and transitioning the FSM.
