On a rainy morning in Lagos, healthcare workers at public hospitals are using voice AI to ease their workload for the first time. Instead of writing patient notes by hand, doctors can now speak, and the AI transcribes their medical reports instantly.
This breakthrough is thanks to Intron, a Nigerian startup founded by Dr. Tobi Olatunji in 2020. Intron’s voice-based AI understands Nigerian accents and medical terms, helping over 56,000 patients across 30 hospitals in Nigeria and Kenya. It reduces paperwork for doctors, allowing them to focus more on care. At University College Hospital in Ibadan, Intron cut radiology report time from 48 hours to just 20 minutes, a 99.3% reduction.
Intron isn’t the only player. Spitch AI, another Lagos startup, launched in late 2024 with a focus on African languages like Yoruba, Hausa, Igbo, and Amharic. Its API tools let companies add voice capabilities to customer service, media, and education platforms without complex machine learning skills. Spitch’s technology is helping Nollywood studios save time and costs by generating synthetic voices for movies.
The Nigerian government is also pitching in. The Ministry of Communications is working with Awarri, a local startup developing Nigeria’s first government-backed large language model. This AI model supports five low-resource Nigerian languages and Nigerian-accented English. Awarri’s LangEasy app crowdsources voice data from everyday Nigerians to improve its system.
Building AI for Nigeria is tough. The startups face challenges like scarce data, costly computing power, and finding skilled researchers. Dr. Olatunji says running AI models costs tens of thousands of dollars each cycle, and hiring experts is difficult due to competition with global tech giants. Still, these startups rely on strong operations, quality control, and partnerships to overcome obstacles.
This new wave of African voice AI is more than tech, it promises to reshape how Nigerians interact with healthcare, legal systems, finance, and media. Intron aims for a future where people can do banking or send money using their own languages, while Spitch plans to enable thousands of developers to build voice tools for Africa’s unique needs.
The rise of these homegrown AI innovations shows a shift towards technology that truly understands and serves local realities, bridging gaps left by global models and creating new opportunities across the continent.
