Enum Value: `jsontextsrtverbose_jsonvttdiarized_json` Example Value:`json` temperaturenumber Optional Sampling temperature between 0 and 1. Higher values (e.g., 0.8) make the output more random, while lower values (e.g., 0.2) make it more focused and deterministic. If set to 0, the model automatically increases temperature using log probability until a certain threshold is reached. languagestring Optional The language of the input audio.
