Language & Voice AI for Africa: From Data to Deployment and Impact

Join us for the Microsoft Research Africa & AI For Good Grand Seminar

Thursday April 30th from 2pm to 5pm EAT

This seminar explores how language and voice AI systems can be built and scaled for African contexts—from community-driven data collection and multilingual foundation models to robust deployment and real-world applications across sectors such as agriculture, health, and public services. We will discuss technical advances, evaluation challenges, and ecosystem partnerships needed to ensure these technologies work for Africa’s linguistic diversity and development priorities.

What Do Our Benchmarks Actually Measure? Evaluation Challenges for African Language AI

This talk will examine the growing gap between advances in language modeling and the evaluation methods used to assess them, drawing on emerging analyses of African language benchmarks to argue that rethinking evaluation is essential for enabling multilingual AI. Future frameworks must better reflect linguistic diversity, community priorities, and the complex sociotechnical contexts in which these languages are used.

Building the Substrate: The Foundry Model for African AI Innovation

This talk outlines the “Foundry Model,” a collaborative framework where empowered research organizations and local experts co-author the essential tools of the trade. Drawing on the origin story and success of a recent large-scale speech and language initiative (‘Waxal’), we demonstrate how community-led data engineering, paired with global research mentorship, creates a multiplier effect. We move beyond the “builder” vs. “user” dichotomy to explore how we can collectively forge a digital commons that empowers every startup and researcher to build the next generation of Africa’s context-aware technology.

Problem Driven Development: The unglamorous road to real world African Voice AI

Bringing Swahili to Life

Korir will share lessons from building Sauti, MsingiAI’s open-source Swahili TTS system, highlighting what it takes to move from data to deployment for a low-resource African language. This includes approaches to data, including curating WAXAL-compatible Kenyan Swahili speech, dealing with code-switching and dialectal variation, and the modeling choices that let us distill efficient, deployable voices that can run close to users. Ultimately, Korir will share what it takes to ship responsibly, and why open, Africa-led voice AI is the only sustainable path to language technology that truly serves the continent.

Multilingual Speech LLMs in Practice

John will give some updates on Sunbird AI’s work with speech-language models for East African languages, aimed at optimising both latency and accuracy. From deployments across Uganda, he’ll build up an interesting picture of what people want to do with such models, and what opportunities we are seeing for further model iteration, debugging, and community collaboration.
