TWB Voice 1.0 - Kanuri is the Kanuri language portion of the TWB Voice 1.0 multilingual speech corpus, created by CLEAR Global (formerly Translators without Borders). It contains approximately 52 hours of read speech recorded by native Kanuri speakers through the TWB Voice platform. The dataset includes 27,723 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.
