Whosper-large

Model Overview

Whosper-large is a fine-tuned version of 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 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

pip install git+https://github.com/sudoping01/[email protected]

Basic Usage

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)
