# TTSAlignment

Defined in: [packages/ai/src/types.ts:2397](https://github.com/TanStack/ai/blob/main/packages/ai/src/types.ts#L2397)

Timings for the generated audio, returned when `timestamps: true` was
requested and the adapter declares `capabilities.timestamps`.

Granularity differs per provider — ElevenLabs reports characters, BytePlus
reports words — so `unit` says which, and the three arrays are parallel.
All times are **seconds**; adapters convert.
