African Language AI

Voice AI built for Africa's languages

27%→13.5%Swahili word error rate — halved through fine-tuning on local data

FiniFlow Labs trains, evaluates, and deploys speech AI systems grounded in African linguistic data. Our first system, SAUTI, delivers accurate Swahili speech recognition and natural voice synthesis through production APIs.

Our Mission

Every African language deserves a voice

Voice AI has transformed how people interact with technology — if they speak English. For the billion-plus speakers of African languages, the technology simply doesn't exist yet.

FiniFlow Labs is building voice AI from the ground up for African languages. Our APIs deliver natural text-to-speech, accurate speech recognition, and intelligent voice agents — engineered for the languages, accents, and infrastructure of the continent.

Research

Grounded in African linguistic data

We build on open datasets and pretrained multilingual models, then apply targeted fine-tuning to close the performance gap between high-resource and African language voice AI systems. All model weights, training configs, and evaluation results are published openly.

SAUTI ASR v1 is now open: Swahili speech recognition for everyone

Off-the-shelf ASR gets Swahili wrong one word in four. SAUTI ASR v1 cuts that in half. The model is open on HuggingFace with a live demo, Python and TypeScript SDKs, and API access.

How we halved Swahili speech recognition errors

Off-the-shelf multilingual ASR gets Swahili wrong one word in four. We fine-tuned on local Swahili data and halved that error rate to 13.5%. Here is what we learned.

Introducing FiniFlow Labs: building African language AI from the ground up

African languages are spoken by over a billion people yet remain largely absent from mainstream AI research. FiniFlow Labs is our answer — a research lab and API platform dedicated to closing that gap.
