modelundefined · enumRequiredPossible values:

textstring · min: 1 · max: 4096Required

The text content to be converted to speech.

voicestring · enumRequired

Name of the voice to be used

Possible values:

stylestringOptional

Determines the style exaggeration of the voice. This setting attempts to amplify the style of the original speaker. It does consume additional computational resources and might increase latency if set to anything other than 0.

response_formatstring · enumOptional

Format of the output content for non-streaming requests. Controls how the generated audio data is encoded in the response.

Default: mp3Possible values:

speednumber · min: 0.25 · max: 4Optional

Adjusts the speed of the voice. A value of 1.0 is the default speed, while values less than 1.0 slow down the speech, and values greater than 1.0 speed it up.

Default: 1
