Silencio

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 don't exist as training data — until we collect them. That's the moat no scraper or synthetic pipeline can cross, and it's why frontier research labs train on 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 & labeling — native-speaker transcription with code-switching support and multi-stage QA, for the languages machine transcription still can't 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're the reason they can answer in every language.
