Help Us Break Down Barriers in Speech Tech

Open Voice is an open source speech dataset (corpus) of native contributors who want to help computer system understand and speak African languages.

For Developers

Contribute to OpenVoice by helping us design and build the product.

For Partners & Sponsor

Sponsor us to advance AI and promote an inclusive African AI future. Gain early access to AI solutions, recognition, and networking opportunities.

For Speech Contributors

Lend your voice to train computers to speak your native language. It all takes a fun language game played on your device.

What is a speech dataset?

Imagine a collection of recordings where people speak in different languages and accents. This data helps computers understand human speech and build better technologies for everyone and we collect them through a fun language game that anyone can play, then make it available for anyone to use for training a machine learning model.
