# Whosper-large

## Model Overview
Whosper-large is a fine-tuned version of [openai/whisper-large-v2](https://huggingface.co/openai/whisper-large-v2) optimized for Wolof speech recognition Senegal's primary language, while maintaining strong multilingual capabilities. Built on OpenAI's Whisper-large-v2, it advances African language processing with notable improvements in Word Error Rate (WER) and Character Error Rate (CER). Whether you're transcribing conversations, building language learning tools, or conducting research, this model is designed for researchers, developers, and students working with Wolof speech data.


### Key Strengths
- **Strong Multilingual**: Excellent performance in Wolof, French, and English
- **Code-Switching**: Handles natural language mixing, especially Wolof-French
- **Consistent Results**: Maintains quality across different languages
- **Open Source**: Released under the [apache-2.0](https://www.apache.org/licenses/LICENSE-2.0) license
- **African NLP**: Supporting African language technology development

## Performance Metrics
- **WER**: 0.2423 
- **CER**: 0.1135 


## Key Features
- Strong multilingual performance (Wolof, French, English)
- Excellent performance on code-switched content
- Consistent performance across different languages

## Limitations
- Outputs in lowercase only
- Limited punctuation support
- Low performances on bad quality audios

## Training Data
Trained on diverse Wolof speech data:

- **ALFFA Public Dataset**
- **FLEURS Dataset**
- **Bus Urbain Dataset**
- **Kallama Dataset**

## Quick Start Guide

### Installation
```bash
pip install git+https://github.com/sudoping01/whosper.git@v1.0.0
```

### Basic Usage
```python
from whosper import WhosperTranscriber

# Initialize the transcriber
transcriber = WhosperTranscriber(model_id="CAYTU/whosper-large") 

# Transcribe an audio file
result = transcriber.transcribe_audio("path/to/your/audio.wav")
print(result)
```
