The available options depend on the encoding type. encoding : typing.Optional[AudioGenerateRequestEncoding] Encoding allows you to specify the expected encoding of your audio output expressivity : typing.Optional[int] Expressive range of the generated speech, on a calm-to-animated axis. Accepted values: `-2`, `-1`, `0`, `1`, `2`. `0` (the default) is the voice's tuned delivery and the production-validated setting, with `-2` the calm end of the range and `2` the animated end. Supported on all Flux voices; applies to the whole request. Beta: behavior may change in future model versions, and non-default values increase the risk of hallucinations and pronunciation errors; audition before shipping. An invalid value is rejected with a `400` — `EXPRESSIVITY_OUT_OF_RANGE` for a value outside the range, `EXPRESSIVITY_INCREMENT_INVALID` for a fractional value. See [Expressivity](/docs/tts-expressivity). sample_rate : typing.Optional[int] Sample Rate specifies the sample rate for the output audio. Based on the encoding, different sample rates are supported. For some encodings, the sample rate is not configurable speed : typing.Optional[float] Speaking rate multiplier that adjusts the pace of generated speech while preserving natural prosody and voice quality. Accepted values run `0.85` to `1.15` in `0.05` increments. Not yet supported in all languages. priority : typing.Optional[typing.Literal["low"]] Processing priority for asynchronous (callback) requests. The only supported value is low. request_options : typing.Optional[RequestOptions] Request-specific configuration. You can pass in configuration such as `chunk_size`, and more to customize the request and response. Returns ------- typing.Iterator[HttpResponse[typing.Iterator[bytes]]] Returns the synthesized audio in the requested encoding as a binary stream. When a `callback` URL is supplied, the request is processed asynchronously and the response body is instead a JSON acknowledgement (Content-Type `application/json`) of the form {"request_id": "..."}, with the audio delivered to the callback URL. Because this endpoint is typed as a binary audio stream, SDK callers that set `callback` receive this JSON acknowledgement through the audio byte iterator as raw bytes and must join the chunks and parse `request_id` themselves.
