GET
List Voice Languages
Read only Returns the language choices supported by one voice as a root array of id (prefixed lang_, the same ID that List Languages returns), code (a short code such as en or hi) and name. 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.
