Welcome to your comprehensive guide on leveraging the Whisper Large V3 (Thai) model for automatic speech recognition (ASR). This powerful model has been fine-tuned to enhance transcription capabilities, especially for Thai language audio.

What is Whisper Large V3?

Whisper Large V3 is a specialized version of the OpenAI Whisper model, optimized particularly for the Thai language using augmented datasets. The model showcases impressive performance with a Word Error Rate (WER) of 6.59 on the common-voice-13 test set.

Step-by-Step Guide to Implement the Model

To get started using the Whisper Large V3 model, you will utilize the Hugging Face Transformers library. Here’s how to set it up:

• Install Necessary Libraries:

  pip install transformers torch

• Import the Required Libraries:

  from transformers import pipeline

• Specify the Model Name and Language:

  MODEL_NAME = "biodatlab/whisper-th-large-v3-combined"  # specify the model name
  lang = "th"  # change to Thai language

• Select the Device:

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

• Create the Pipeline:

  pipe = pipeline(
      task="automatic-speech-recognition",
      model=MODEL_NAME,
      chunk_length_s=30,
      device=device,
  )

• Set Decoder IDs and Transcribe Audio:

  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

Understanding the Code: An Analogy

Imagine you’re preparing a delicious meal. You need to gather your ingredients (import libraries), choose a recipe (specify model name and language), and select your cooking method (select device). The pipeline is like the cooking process where you mix all the ingredients according to the recipe. Finally, just as you serve the meal, you give the audio file to the pipeline to transcribe. Each step is crucial to ensure that the end product (transcribed text) is both accurate and flavorful!

Troubleshooting Tips

If you encounter issues while implementing the model, here are some troubleshooting suggestions to help you out:

• Installation Errors: Ensure that all libraries are correctly installed and compatible with your Python version.
• Model Loading Issues: Verify the model name and internet connection, as it needs to download the model files from Hugging Face.
• Audio File Not Transcribed: Ensure the audio file path is correct and that the file format is supported. Convert it to a compatible format if needed.
• Performance Lag: If the model runs slowly, consider running it on a machine with a powerful GPU or reduce the audio chunk length.
