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.
