# Wolof Audio Dataset

The **Wolof Audio Dataset** is a collection of audio recordings and their corresponding transcriptions in Wolof. This dataset is designed to support the development of Automatic Speech Recognition (ASR) models for the Wolof language. It was created by combining three existing datasets:

- **ALFFA**: Available at [serge-wilson/wolof_speech_transcription](https://huggingface.co/datasets/serge-wilson/wolof_speech_transcription)
- **FLEURS**: Available at [vonewman/fleurs-wolof-dataset](https://huggingface.co/datasets/vonewman/fleurs-wolof-dataset)
- **Urban Bus Wolof Speech Dataset**: Available at [vonewman/urban-bus-wolof](https://huggingface.co/datasets/vonewman/urban-bus-wolof)
- **Kallama Dataset**: Available at [Moustapha91/wolof_kalama_TTS](https://huggingface.co/datasets/Moustapha91/wolof_kalama_TTS)

## Dataset Description

- **Language**: Wolof (`wo`)
- **Domain**: General speech and urban transportation
- **Data Type**: Audio recordings and transcriptions
- **Audio Format**: Varies (e.g., WAV, MP3)
- **Sampling Rate**: 16 kHz
- **Total Examples**: 24,346
  - **Training Set**: 20224 examples
  - **Test Set**: 4122 examples

### Features

- `audio`: An audio file containing speech in Wolof.
  - **Format**: Varies (e.g., WAV, MP3)
  - **Sampling Rate**: 16 kHz
- `sentence`: The textual transcription of the audio in Wolof.
- `source`: The origin of the example, either `'alffa'`, `'fleurs'`, `'urban_bus'`, or `'kallama'`

### Dataset Structure

#### Splits

The dataset is divided into two splits:

| Split  | Number of Examples |
|--------|---------------------|
| Train  | 28,807              |
| Test   | 6,268               |

## Usage Example

Here's how to load and use this dataset with the 🤗 Datasets library:

```python
from datasets import load_dataset

# Load the dataset
dataset = load_dataset("vonewman/wolof-audio-data")

# Access an example from the 'train' split
print(dataset['train'][0])

# Expected output:
# {
#   'audio': {
#     'path': '.../train/audio/<audio_file>',
#     'array': array([...]),
#     'sampling_rate': 16000
#   },
#   'sentence': 'Transcription of the audio in Wolof',
#   'source': 'alffa'  # or 'fleurs' or 'urban_bus' or 'kallama'
# }
