Request Parameters

Parameter	Required	Type	Default	Allowed values / range	Description

`language`	No	string	—	ISO 639-1, e.g. `en`	Omit this to let the model detect the language — that is the default. `auto` means the same. Set it to force one of the recording.
`prompt`	No	string	—	up to 2,000 characters	Bias the transcription toward expected wording — names, jargon, spellings.

Voices

Optional prompt biases the transcription toward expected wording; temperature accepts 0–1.
