Choosing a voice ID

Browse the Voices page, open a voice and copy its Voice ID. Pass that exact value as voice; the display name and dialect label are not identifiers.

Your API key can use voices owned by its account and voices published for public use. Knowing a private voice ID does not grant access. A deleted, unavailable or unauthorized voice returns an error; the API does not silently substitute another voice.

To create a voice from your recording, follow the voice cloning guide. Once encoding finishes, use the new voice ID in the same speech request.
