Deterministic, consistent output

Definition

The voice catalog is the library of voices you synthesize with: 1,500+ across 30+ languages. You select one by its voice ID in each request. For anything the catalog does not cover, a cloned voice slots in by ID the same way.

Breadth

A large catalog means you match voice to use case instead of forcing one voice everywhere. A warm narrator for an audiobook, a crisp voice for IVR, a distinct set for a game cast, all from the same library across 30+ languages.

Consistency

Every voice ID is deterministic. The same ID produces the same voice on every call, so long-form projects, chapters, episodes, course modules, stay consistent with no drift between the first synthesis and the last.

Beyond the catalog

When you need a voice that is not in the library, clone one and reference its ID exactly like a catalog voice. See the voice cloning page and the language guide.

FAQ

Frequently asked questions

How many voices are in the catalog?

The catalog has 1,500+ voices across 30+ languages. You select a voice by its ID in the synthesis request, and because output is deterministic, the same voice ID sounds identical across every call, which keeps long-form projects consistent.

How do I choose a voice?

Browse the catalog by language and style, pick a voice, and pass its voice ID to the API. For a custom or branded voice beyond the catalog, clone one and use its ID the same way.

Are voices consistent across requests?

Yes. A given voice ID is deterministic, so chapter one and chapter twenty, or episode one and episode fifty, sound like the same voice with no drift.
