Features
Transcribes live audio streams to text over the Live API.
speech_to_text
Continuous bidirectional streaming over the Live API (bidiGenerateContent) with speculative interim transcripts (interim_input_transcription) ahead of finalized ones (input_transcription), no published latency SLA, and sessions up to 10 minutes.
streaming
Automatically detects and transcribes 85+ languages, including code-switching.
multilingual_transcription
Emits speculative interim_input_transcription events while the speaker is talking, followed by finalized input_transcription events when speech is finalized.
interim_transcripts
Biases recognition toward up to 1,000 supplied terms, acronyms, brand names, or proper nouns (best results with up to 100).
custom_vocabulary
Optional SMART mode removes filler words, stuttering, and false starts and applies structured formatting; default is VERBATIM.
smart_transcription
Automatic server-side VAD (default), hybrid (server detects speech start, client ends via audio_stream_end), or manual push-to-talk (automatic_activity_detection.disabled with explicit activity_start/activity_end signals).
vad_modes
