# Whisper Small sinhala - Lingalingeswaran

This model is a fine-tuned version of [openai/whisper-small](https://huggingface.co/openai/whisper-small) on the Lingalingeswaran/asr-sinhala-dataset_json_v1 dataset.


## Model description

This Whisper model has been fine-tuned specifically for the Sinhala language using the Common Voice 11.0 dataset. It is designed to handle tasks such as speech-to-text transcription and language identification, making it suitable for applications where Sinhala is a primary language of interest. The fine-tuning process focused on enhancing performance for Sinhala, aiming to reduce the error rate in transcriptions and improve general accuracy.

## Intended uses & limitations
Intended Uses:
Speech-to-text transcription in Sinhala

Limitations:
May not perform as well on languages or dialects that are not well-represented in the Common Voice dataset.
Higher Word Error Rate (WER) in noisy environments or with speakers who have heavy accents not covered in the training data.
The model is optimized for Sinhala; performance in other languages may be suboptimal.

## Training and evaluation data

The training data for this model consists of voice recordings in Sinhala from the Mozilla-foundation/Common Voice 11.0 dataset. The dataset is a crowd-sourced collection of transcribed speech, ensuring diversity in terms of speaker accents, age groups, and speech styles.
### Training hyperparameters

The following hyperparameters were used during training:
- learning_rate: 1e-05
- train_batch_size: 16
- eval_batch_size: 8
- seed: 42
- optimizer: Use OptimizerNames.ADAMW_TORCH with betas=(0.9,0.999) and epsilon=1e-08 and optimizer_args=No additional optimizer arguments
- lr_scheduler_type: linear
- lr_scheduler_warmup_steps: 500
- training_steps: 4000
- mixed_precision_training: Native AMP

<!-- ### Training results -->

## Example Usage

Here is an example of how to use the model for Sinhala speech recognition with Gradio:

```python
import gradio as gr
from transformers import pipeline

# Initialize the pipeline with the specified model
pipe = pipeline(model="Lingalingeswaran/whisper-small-sinhala")

def transcribe(audio):
    # Transcribe the audio file to text
    text = pipe(audio)["text"]
    return text

# Create the Gradio interface

iface = gr.Interface(
    fn=transcribe,
    inputs=gr.Audio(sources=["microphone", "upload"], type="filepath"),
    outputs="text",
    title="Whisper Small Sinhala",
    description="Realtime demo for Sinhala speech recognition using a fine-tuned Whisper small model.",
)

# Launch the interface
if __name__ == "__main__":
    iface.launch()
