Intended Use
This dataset can be used for speech processing, including text-to-speech, and ASR.
This dataset contains audio recordings of Bible verses in Ehugbo, a dialect of Igbo (a Niger-Congo language spoken in Nigeria). The dataset was curated by Ukachi Agnes Eze-Mbey as part of the 2025 NaijaVoices Micro-Grants Heritage project.
This dataset contains verse-by-verse Bible translations, where each recording corresponds to a specific Bible verse. The recordings are segmented at the verse level, making this dataset particularly valuable for fine-grained linguistic analysis, verse-level alignment studies, and Bible translation research. The dataset covers six books from the New Testament: Acts of Apostles, Ephesians, Galatians, John, Revelations, and Romans.
Note: This dataset includes explicit permission from the Nigeria Bible Translation Trust to use excerpts of the Ehugbo New Testament Bible, as documented in the copyright approval letter.
