# Vai Speech-Text Parallel Dataset |
|
|
|
|
|
## Dataset Description |
|
|
|
|
|
This dataset contains 23286 parallel speech-text pairs for Vai, a language spoken primarily in Ghana. The dataset consists of audio recordings paired with their corresponding text transcriptions, making it suitable for automatic speech recognition (ASR) and text-to-speech (TTS) tasks. |
|
|
|
|
|
### Dataset Summary |
|
|
|
|
|
- **Language**: Vai - `vai` |
|
|
- **Task**: Speech Recognition, Text-to-Speech |
|
|
- **Size**: 23286 audio files > 1KB (small/corrupted files filtered out) |
|
|
- **Format**: WAV audio files with corresponding text files |
|
|
- **Modalities**: Audio + Text |
|
|
|
|
|
### Supported Tasks |
|
|
|
|
|
- **Automatic Speech Recognition (ASR)**: Train models to convert Vai speech to text |
|
|
- **Text-to-Speech (TTS)**: Use parallel data for TTS model development |
|
|
- **Keyword Spotting**: Identify specific Vai words in audio |
|
|
- **Phonetic Analysis**: Study Vai pronunciation patterns |
|
|

## Dataset Structure |
|
|
|
|
|
### Data Fields |
|
|
|
|
|
- `audio`: Audio file in WAV format |
|
|
- `text`: Corresponding text (latin) transcription from paired text file. You can use the [vai-latin.csv](./vai-latin.csv) file to translate latin form of Vai text into the traditional Vai script. |
|
|
|
|
|
|
|
|
### Data Splits |
|
|
|
|
|
The dataset contains a single training split with 23286 filtered audio-text pairs. |
|
|
|
|
|
## Dataset Creation |
|
|
|
|
|
### Source Data |
|
|
|
|
|
The audio data has been sourced ethically from consenting contributors. To protect the privacy of the original authors and speakers, specific source information cannot be shared publicly. |
|
|
|
|
|
### Data Processing |
|
|
|
|
|
1. Audio files and corresponding text files were collected from organized folder structure |
|
|
2. Text content was read from separate `.txt` files with matching filenames |
|
|
3. Files smaller than 1KB were filtered out to ensure audio quality |
|
|
4. Empty text files were excluded from the dataset |
|
|
5. Audio was processed using the [MMS-300M-1130 Forced Aligner](https://huggingface.co/MahmoudAshraf/mms-300m-1130-forced-aligner) tool for alignment and quality assurance |
|
|
|
|
|
### Annotations |
|
|
|
|
|
Text annotations are stored in separate text files with matching filenames to the audio files, representing the spoken content in each audio recording. |
|
|
|
|
|
## Considerations for Using the Data |
|
|
|
|
|
### Social Impact of Dataset |
|
|
|
|
|
This dataset contributes to the preservation and digital representation of Vai, supporting: |
|
|
- Language technology development for underrepresented languages |
|
|
- Educational resources for Vai language learning |
|
|
- Cultural preservation through digital archives |
|
|
|
|
|
### Discussion of Biases |
|
|
|
|
|
- The dataset may reflect the pronunciation patterns and dialects of specific regions or speakers |
|
|
- Audio quality and recording conditions may vary across samples |
|
|
- The vocabulary is limited to the words present in the collected samples |
|
|
|
|
|
### Other Known Limitations |
|
|
|
|
|
- Limited vocabulary scope (word-level rather than sentence-level) |
|
|
- Potential audio quality variations |
|
|
- Regional dialect representation may be uneven |
|
|
