Silencio Voice AI announced the largest consented African-language speech data commitment in production, consisting of 8 languages including Swahili, Amharic, Yoruba, Hausa, Igbo, Oromo, Taita, and Tigrinya, with a combined of 50,000 hours across the 8 languages.

Silencio is the voice data infrastructure behind the world's best voice AI. The one dataset you can't scrape. Voice AI today reaches fewer than 3% of the world's 7,000 languages. The 3.7 billion people it can't hear simply do not exist as training data until their voices are collected. That is the moat no scraper or synthetic pipeline can cross, and it is why frontier AI labs and Fortune 100 companies train on data sourced from Silencio. Any language, any accent, anywhere there are people. Real human speech across 1,000+ languages and dialects in 180+ countries. Not scraped, not synthetic. What you get: - Off-the-shelf datasets: pre-collected multilingual voice and audio, structured by language, region, and use case. License in days. - On-demand collection: custom data sourced to spec, in the languages and acoustic conditions your models actually fail on. - Transcription and labelling: native-speaker transcription with code-switching support and multi-stage QA, for the languages machine transcription still cannot handle. Provenance is IP-clean end to end: documented consent, full traceability, aligned with the EU AI Act, GDPR, and forthcoming US data provenance rules. The data we ship is the data your procurement team will sign for. Voice is how the world will talk to machines. We are the reason they can answer in every language. → https://www.silencio.network/
