Whisper Medium (Thai): Combined V2

This model is a fine-tuned version of biodatlab/whisper-medium-th-1000iter on the mozilla-foundation/common_voice_11_0 th dataset. It achieves the following results on the evaluation set:

  • Loss: 0.1475
  • WER: 13.03 (without Tokenizer)
  • WER: 8.44 (with Deepcut Tokenizer)

Model description

Use the model with huggingface's transformers as follows:

from transformers import pipeline

MODEL_NAME = "biodatlab/whisper-medium-th-combined-v2"  # specify the model name
lang = "th"  # change to Thai langauge

device = 0 if torch.cuda.is_available() else "cpu"

pipe = pipeline(
    task="automatic-speech-recognition",
    model=MODEL_NAME,
    chunk_length_s=30,
    device=device,
)
pipe.model.config.forced_decoder_ids = pipe.tokenizer.get_decoder_prompt_ids(
  language=lang,
  task="transcribe"
)
text = pipe("audio.mp3")["text"] # give audio mp3 and transcribe text
