Configuring the Model

export ASR_MODEL=base

Available ASR_MODELs are tiny, base, small, medium, large (only OpenAI Whisper), large-v1, large-v2 and large-v3.

For English-only applications, the .en models tend to perform better, especially for the tiny.en and base.en models. We observed that the difference becomes less significant for the small.en and medium.en models.
