TranscriptionPreflightEvent
Emitted when a provider sends a preflight/eager-end-of-turn signal.
Defined in: src/core/events/types.ts:232
Emitted when a provider sends a preflight/eager-end-of-turn signal.
Remarks
DeepgramFlux (e.g., flux-general-en) emits this before speech_final to allow downstream stages (LLM) to start generating speculatively. The text may change slightly when the confirmed speech_final arrives.
This event is only relevant when EagerLLMConfig is enabled.
Example
agent.on('transcription.preflight', (event) => {
console.log('Preflight transcript:', event.text);
});
See
- EagerLLMConfig for enabling the eager LLM pipeline
- TranscriptionSpeechFinalEvent for the confirmed result
- TranscriptionEvent for all transcription event types
