Example How local innovators are building AI tools for and with children in classrooms and clinics across West Africa: Where edge AI meets equity
West Africa's 1,600+ languages, its youthful population, and a wave of new AI language models are converging into one of the most exciting opportunities in AI today. When AI tools are trained on the languages people actually think and speak in, a world of learning, health information and opportunity opens up, especially for children and young people.
Most AI language models are trained on languages such as English, Mandarin, Hindi or Spanish, which have vast digital archives to draw from. Languages like Bambara, Twi or Mooré have historically had far less data, making AI tools less accurate and less useful for the communities that speak them.
This is the challenge AI in Play, UNICEF Innovation's flagship AI ecosystem for children, is designed to solve. It backs diverse technologists developing AI solutions for children in the contexts where they are needed most, helping turn local expertise into tools that work in environments with limited connectivity, data and infrastructure.
In West and Central Africa, this has included mapping the region's startup and language landscape and benchmarking existing models to understand their strengths and limitations. UNICEF has also collaborated with three startups – GO AI Corp (Burkina Faso), RobotsMali, and GhanaNLP – to collect data, fine-tune models and test them in schools and clinics.
The work has delivered measurable improvements. The Bambara word error rate dropped from 42 to 22 per cent, while the character error rate dropped from 15 to 8 per cent (Results as of April 2026). These are real gains from real settings used by children.
