List Voice Accents
Read only
Returns the distinct accent values across every non-deleted voice in the DialNexa catalog, optionally narrowed by
provider. An accent describes how a voice sounds, for example an Indian, American or British English voice; it is a label, not a language code. The response is a root array of accent names, for example indian, american and british. Pass one of them as the accent filter on 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.
accent filter on List Voices accepts indian, british, american, canadian, african, australian and swedish; any other value returns 400.
