Preamble:
Much of African culture and heritage is rooted in orality. Thus the preservation of culture is predicated on the preservation, use, and mainstreaming of local languages. This is why licensing African language datasets is vital to ensure that data creation, sharing, and use uphold the rights and interests of local communities.
Well-defined licenses promote transparency and fairness by specifying how data can be accessed, reused, or commercialized, while safeguarding cultural knowledge, linguistic heritage, benefit sharing, and collective ownership, while also preventing exploitation by external actors and ensuring that the benefits are equitably shared.
The Dholuo speech dataset was created by participants from the Dholuo language community in Kenya, supported by researchers from Maseno Centre for Applied Artificial Intelligence (MCAAI), Maseno University, and researchers from the Center for Intellectual Property and Information Technology Law (CIPIT), Strathmore University.
Through a consultative process and with the support of CIPIT and MCAAI, community representatives helped determine the most suitable licensing framework and enhanced their understanding of intellectual property principles and the nuances differentiating various licensing options. The representatives were also involved in the creation of this dataset which was created between October 2025 and November 2025 with support from Mozilla Foundation and GIZ FAIR Forward.
We extend a profound and sincere nod of appreciation to the dedicated Dholuo community, the meticulous data collectors, and the visionary license creators who made this pathway possible.
The Dholuo Speech dataset is licensed under the Nwulite Obodo Open Data License (NOODL). View the license at NOODL License. It is applied to the DhoNam: Dholuo speech dataset, covering adult speakers from the Kenyan Dholuo community.
