Whisper Tamil Medium

🚀 Whisper Tamil Medium

This model is a fine - tuned version of [openai/whisper - medium](https://huggingface.co/openai/whisper - medium) on Tamil data from multiple public ASR corpuses, aiming to enhance automatic speech recognition performance in Tamil.

🚀 Quick Start

This model is a fine - tuned version of openai/whisper-medium on the Tamil data available from multiple publicly available ASR corpuses. It has been fine - tuned as a part of the Whisper fine - tuning sprint.

NOTE: The code used to train this model is available for re - use in the whisper-finetune repository.

✨ Features

• Fine - tuned on multiple publicly available Tamil ASR corpuses.
• Code for training and evaluation is open - sourced and reusable.
• Supports faster inference using whisper - jax.

📦 Installation

The installation steps are not explicitly provided in the original README. However, relevant libraries and dependencies can be installed as per the requirements in the whisper-finetune repository.

💻 Usage Examples

Basic Usage

In order to infer a single audio file using this model, the following code snippet can be used:

>>> import torch
>>> from transformers import pipeline

>>> # path to the audio file to be transcribed
>>> audio = "/path/to/audio.format"
>>> device = "cuda:0" if torch.cuda.is_available() else "cpu"

>>> transcribe = pipeline(task="automatic-speech-recognition", model="vasista22/whisper-tamil-medium", chunk_length_s=30, device=device)
>>> transcribe.model.config.forced_decoder_ids = transcribe.tokenizer.get_decoder_prompt_ids(language="ta", task="transcribe")

>>> print('Transcription: ', transcribe(audio)["text"])

Advanced Usage

For faster inference of whisper models, the whisper-jax library can be used. Please follow the necessary installation steps as mentioned here, before using the following code snippet:

>>> import jax.numpy as jnp
>>> from whisper_jax import FlaxWhisperForConditionalGeneration, FlaxWhisperPipline

>>> # path to the audio file to be transcribed
>>> audio = "/path/to/audio.format"

>>> transcribe = FlaxWhisperPipline("vasista22/whisper-tamil-medium", batch_size=16)
>>> transcribe.model.config.forced_decoder_ids = transcribe.tokenizer.get_decoder_prompt_ids(language="ta", task="transcribe")

>>> print('Transcription: ', transcribe(audio)["text"])

📚 Documentation

In order to evaluate this model on an entire dataset, the evaluation codes available in the whisper-finetune repository can be used. The same repository also provides the scripts for faster inference using whisper - jax.
