error: Failed to init model as VAD

Error message

error: Failed to init model as VAD

What it means

Initializing the whisper model in VAD mode failed. Guard: verify the model supports VAD before selecting that mode; fail LoadModel with a clear error otherwise.

Solutions

1. Verify the model file supports VAD mode.
2. Check that the model path is correct and the file is not corrupted.
3. Ensure enough memory is available to initialize the model.
