automatic-speech-recognition model by undefined. 49,28,734 downloads.

Unique: Enables full-model fine-tuning on domain-specific data using standard PyTorch training loops, leveraging pretrained encoder-decoder representations for efficient adaptation. Supports distributed training and mixed-precision training for large-scale fine-tuning.
