Choosing an Endpoint

Reson8 offers three speech-to-text endpoints. Which one to use depends on where your audio comes from and what you want to do with the result.

  • Prerecorded - Upload a complete audio file over REST and receive the full transcript in one response.
  • Realtime - Stream live audio over WebSocket and receive transcripts as the speech is recognized.
  • Turns - Stream live audio over WebSocket and receive events when a speaker starts and stops talking, with the transcript of each turn.
