List Transcribers
Read only
Returns every speech-to-text transcriber that can be an agent’s primary transcriber. Each entry includes the transcriber’s stable
id, the upstream provider (for example deepgram, sarvam, soniox), the provider’s model_id, the display name, a description, the supported_language_codes it is limited to (null when it is not limited), and the is_primary and is_fallback flags. Use this endpoint as the source of truth when configuring an agent’s transcription settings, the transcriber you choose determines how accurately the agent understands what the caller says, which is especially important for accented speech, technical terminology, and non-English languages.
When to use this
- Agent build UIs: populate the transcriber selector when creating or editing an agent.
- Language coverage checks: confirm the transcriber supports every language an agent is configured for; publishing checks this too.
- Cost optimization: switch high-volume use cases to lower-cost engines when accuracy budget allows.
