TWB Voice 1.0 - Hausa is the Hausa language portion of the TWB Voice 1.0 multilingual speech corpus, created by CLEAR Global (formerly Translators without Borders). It contains approximately 58 hours of read speech recorded by native Hausa speakers through the TWB Voice platform. The dataset includes 36,665 recordings across train, dev, test, rejected, and pending splits, with transcriptions and speaker demographic metadata (age, gender, education level, country of origin). Audio is in WAV format at 48kHz. The dataset was created to support automatic speech recognition (ASR) development for underrepresented languages, with funding from the Patrick J. McGovern Foundation.

Ethical Review
All speakers consented to data collection and open publishing. Speaker identities are anonymized using user IDs. Dataset is gated for compliance with privacy and data protection laws (e.g. GDPR). By downloading, users accept data controller responsibilities under the Dataset Access Terms (https://huggingface.co/datasets/CLEAR-Global/TWB-Voice-dataset-access-terms), including handling data subject rights requests and data breach notifications.
Intended Use
Training and evaluation of automatic speech recognition (ASR) systems for Hausa, speaker recognition research, language identification, and speech synthesis/TTS development.
Data was collected through the TWB Voice platform coordinated by CLEAR Global. Native Hausa speakers read prompted text, and recordings underwent human review by native speakers. This is the Hausa subset of the full TWB Voice 1.0 dataset on HuggingFace.
| Split | Recordings | Hours |
|---|---|---|
| train | 26,996 | 43.79 |
| dev | 2,540 | 4.03 |
| test | 4,591 | 6.56 |
| rejected | 1,265 | 2.25 |
| pending | 1,273 | 1.48 |
| Total | 36,665 | 58.11 |
Splits ensure no speaker overlap between train/dev/test while maintaining 80/10/10 duration ratios. Rejected and pending recordings are preserved in separate splits.
| Gender | Hours |
|---|---|
| Male | 38.82 |
| Female | 15.56 |
