Gemini 3.5 Transcribe now available on AI Gateway
Gemini 3.5 Transcribe adds batch and live WebSocket transcription to AI Gateway, with automatic language detection, 85+ languages, and custom vocabulary.
**Gemini 3.5 Transcribe** has separate models for complete recordings and live WebSocket transcription. It supports **85+ languages**, automatic language detection, language switching, and custom vocabulary.
Use batch transcription for stored agent inputs and **AI SDK V7 streamTranscribe** when an agent needs an updating microphone transcript; declare the raw audio format explicitly for live streams.
**Gemini 3.5 Transcribe** has separate models for complete recordings and live WebSocket transcription. It supports **85+ languages**, automatic language detection, language switching, and custom vocabulary. Use batch transcription for stored agent inputs and **AI SDK V7 streamTranscribe** when an agent needs an updating microphone transcript; declare the raw audio format explicitly for live streams. The material reports no accuracy, latency, speaker-separation, or cost results, and the streaming AI SDK functions shown are marked experimental.
This turns Gateway’s general streaming-transcription capability into a concrete split between stored-recording and live-input models, with multilingual switching, custom vocabulary, and an explicit raw-audio contract. It broadens deployable voice-input workflows but does not establish a production default because streaming functions are experimental and accuracy, latency, diarization, and cost remain unmeasured.
