Live transcription — text back while they're still talking

August 18, 2026

Speech-to-text now works as audio arrives instead of only after a recording ends. Each sentence comes back the moment the speaker finishes it, so a voice agent can start responding before the person has stopped talking.

Open a WebSocket to wss://api.openadapter.in/v1/realtime/transcribe, send microphone audio, and read transcripts as they land. Your normal API key works — nothing to enable.

Available on parakeet, whisper-1, whisper-large-v3 and whisper-large-v3-turbo.

You're charged per transcribed sentence, not per connection or per second of audio — an open socket with nobody talking costs nothing.
