temperature (float or list of float, optional) — The temperature to be used for generation. Passing a single float value and do_sample=True activates generation using sampling. For long-form transcription, temperature fallback can be activated by passing a list of float values such as (0.0, 0.2, 0.4, 0.6, 0.8, 1.0). As shown in the the Whisper paper, this can help to improve performance.

Opened #529 to address this. ASROptions.temperatures now accepts a single float or a comma-separated list (e.g. 0.0,0.2,0.4,0.6,0.8,1.0) as a query param, which is forwarded as-is to whisperx → faster-whisper. The underlying chain already supports List[float] natively (whisperx's own default is [0.0, 0.2, 0.4, 0.6, 0.8, 1.0]); the limitation was only in our pydantic schema.
