List Voice Accents
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 every accent option available across voices on the platform. Accents refine pronunciation style within a language family, for example, within the English language family you can pick between Indian (en-IN), American (en-US), and British (en-GB) accents. Each entry includes the accent’s id, display name, and BCP-47 code so you can match it to the voice catalogue returned by List Voices.

When to use this

  • Voice picker UIs: render an accent filter alongside language and gender so prompt authors can find voices that match the listener’s region.
  • Localization tooling: pre-select the right accent when an agent is deployed in a specific country or region.
  • Brand consistency checks: confirm an agent is using the accent your brand guidelines call for before publishing changes through Update Agent.
Not every voice supports every accent. After filtering by accent, intersect with the voices returned by List Voices to find usable combinations.

Errors

  • 401 Unauthorized is returned when the API key is missing or revoked.
