Welcome to the world of Automatic Speech Recognition (ASR) with Whisper Tiny Thai! This guide will walk you through how to utilize this fine-tuned model for your own speech transcription needs. Let’s break it down into digestible parts.

What is Whisper Tiny Thai?

Whisper Tiny Thai is a refined version of the OpenAI Whisper model, specifically trained on the Mozilla Foundation’s Common Voice dataset for the Thai language. This model is designed to enhance speech recognition capabilities in applications that require understanding Thai speech.

How to Get Started

To use Whisper Tiny Thai, follow these steps:

• Install Required Libraries: You will need to have several libraries installed. If you haven’t done so already, ensure you have these versions or higher:
• Transformers (4.26.0.dev0)
• Pytorch (1.13.0+cu117)
• Datasets (2.7.1.dev0)
• Tokenizers (0.13.2)
• Load the Model: Utilize the appropriate code to load the Whisper Tiny Thai model.

from transformers import WhisperForConditionalGeneration, WhisperTokenizer

    tokenizer = WhisperTokenizer.from_pretrained("openai/whisper-small-th")
    model = WhisperForConditionalGeneration.from_pretrained("openai/whisper-small-th")

• Prepare Your Audio Input: Ensure your audio input is in a compatible format and has clear speech.
• Transcription: Use the model to transcribe the speech from audio.

import torch

    audio = "path_to_your_audio.wav"
    input_values = tokenizer(audio, return_tensors="pt").input_values
    with torch.no_grad():
        predicted_ids = model.generate(input_values)
    transcription = tokenizer.batch_decode(predicted_ids, skip_special_tokens=True)[0]

Interpreting the Results

The results of this model yield two critical metrics:

• Loss: A measure indicating how well the model performed during training. Lower values are preferable, confirming the model’s accuracy.
• Word Error Rate (WER): This metric shows how good the model is at transcribing spoken words accurately. A lower WER indicates better performance, with the Whisper Tiny Thai achieving a WER of 14.69.

Understanding the Training Procedure

Imagine training a team of athletes. You focus on various parameters like the intensity of the workouts (learning rate), the size of the team training (batch size), and how to adapt to changes in performance (optimizer). Similarly, this model went through rigorous training using hyperparameters such as:

• Learning Rate: 1e-05
• Batch Sizes: 64 for training, 32 for evaluation
• Optimizer: Adam with specific settings

These configurations allow the Whisper Tiny Thai model to refine its skills over 7000 training steps, much like athletes would improve over countless drills and competitions.

Troubleshooting

If you encounter challenges while using Whisper Tiny Thai, consider the following troubleshooting ideas:

• Model Not Loading: Ensure that the necessary libraries are properly installed and updated.
• Inaccurate Transcriptions: Check the audio quality and clarity, as background noise can significantly affect the WER.
• Memory Issues: If running the model causes memory errors, try reducing the batch size.
