Developers – Voice Agent API

Changelog

Developers – Voice Agent API

  • Added documentation for the audio.input.transcription.keyterms parameter, which lets you supply up to 100 terms (max 50 characters each) to bias transcription toward domain-specific vocabulary such as product names, proper nouns, and technical terms. The parameter can be updated mid-session via session.update.
  • New “Keyterms” section includes usage details and code examples (Python and JavaScript) showing how to configure keyterms in a session update.
