Africa-focused voice AI startup (formerly Intron Health, rebranded mid-2025 as they expanded beyond healthcare). Builds the "infrastructure layer for voice interactions across Africa." Develops the Sahara model family: Sahara-Optimus (ASR for 300+ African accents, 92%+ accuracy), Sahara-Nova (real-time streaming), Sahara-TTS (80+ voices, 40+ accents, 13 countries), Sahara-Voice-Lock (biometric voice auth), and upcoming Sahara-Titan (multilingual ASR for 20 African languages) and Sahara-Primus (multilingual TTS). Proprietary AccentMix algorithm trained on 3.5M+ audio clips from 18,000+ speakers across 30+ countries. Deployed in 30+ hospitals across 5 markets (Nigeria, Kenya, Rwanda, South Africa, Uganda). Also deployed for court transcription (Ogun State Judiciary) and fintech call centers (Branch International). Created major open datasets including AfriSpeech-200 (200hrs, 120 accents) and AfriMed-QA (15,275 medical questions, 32 specialties, 16 countries).
Directly relevant to UNICEF's healthcare AI goals. Sahara-Titan will cover 20 African languages including Hausa, Yoruba, Igbo. AfriSpeech-200 and AfriMed-QA provide critical benchmarks for evaluating AI tools in African healthcare settings. Already deployed in Rwanda (Ministry of Health nationwide), Nigeria, Kenya, Uganda. Gates Foundation/Google/PATH partnership for LLM evaluation aligns with UNICEF's need to assess AI tool readiness.
Formerly "Intron Health", rebranded mid-2025 as they expanded beyond healthcare into legal, fintech, and other sectors. Currently focused on accented English -- Sahara-Titan (local African languages) is still in development. NaijaVoices lists Intron as a partner. Chris Emezue (NaijaVoices) co-authored AfriSpeech-200 and AfriNames papers. Real-world impact: reduced radiology result wait times from 48 hours to 20 minutes; court transcription times nearly halved.
