whisat

Model trained in int8 with LoRA

Usage:

prepare pipeline, providing any custom generate_kwargs supprted by https://huggingface.co/docs/transformers/v4.40.0/en/main_classes/text_generation#transformers.GenerationConfig

asr_model=prepare_pipeline(
        model_dir='.', # wherever you save the model
        generate_kwargs={
                'max_new_tokens':112,
                'num_beams':1,
                'repetition_penalty':1,
                'do_sample':False
                            }
                )

run ASR:

asr_model(audio_path)

run ASR on full directory in audio_dir: If generate_kwargs not specified, will give you (deterministic) greedy decoding with up to 112 tokens generated, no repetition penalty

        audio_dir, 
        out_dir = '../whisat_results/',
        model_dir=".",
)

Training information:

• Training script: tune_hf_whisper.py
