Get Voice Language Details
Read only
Recommended. This endpoint is part of the public /v1 API reference and is the supported path for new integrations. See the migration guide for versioning guidance.
Returns the language choices supported by one voice. Use this endpoint when a voice picker needs to show per-voice language options before saving an agent.

When to use this

  • Voice pickers: after the user selects a voice, show only the languages that voice actually supports.
  • Pre-save validation: confirm the language_id you are about to set on an agent is supported by its voice_id, so Create Agent or Update Agent does not fail validation.
  • Multilingual rollouts: check whether one voice can cover all your target languages or whether you need a different voice per market.
