Silencio AI is the data infrastructure behind the world's best voice AI. Any language, any accent, anywhere there are people, ethically sourced with clear consent and full traceability. Off-the-shelf datasets, on-demand collection, and human transcription. Not scraped. Not synthetic. Real human voice from 2.5 million contributors across 180+ countries, and Fortune 100 companies and frontier research labs already train on it. Voice AI reaches fewer than 3% of the world's 7,000 languages. The 3.7 billion it can't hear don't exist as training data until we collect them. That's the moat no scraper can cross. Voice is how the world will talk to machines, and we'll be the reason they can answer in every language.SilencioAIisthedatainfrastructurebehindtheworld'sbestvoiceAI.Anylanguage,anyaccent,anywheretherearepeople,ethicallysourcedwithclearconsentandfulltraceability.Off-the-shelfdatasets,on-demandcollection,andhumantranscription.Notscraped.Notsynthetic.Realhumanvoicefrom2.5millioncontributorsacross180+countries,andFortune100companiesandfrontierresearchlabsalreadytrainonit.VoiceAIreachesfewerthan3%oftheworld's7,000languages.The3.7billionitcan'theardon'texistastrainingdatauntilwecollectthem.That'sthemoatnoscrapercancross.Voiceishowtheworldwilltalktomachines,andwe'llbethereasontheycananswerineverylanguage.

The voice data layer for AI

On Demand Collection

Custom data sourced to spec across 1,000+ languages and dialects in 180+ countries. Specify what you need, the network delivers.

Off-the-shelf datasets

Pre-collected multilingual voice and audio, structured by language, region, and use case. License and integrate in days.

Transcription and data labeling

Native-speaker transcription with code-switching support and multi-stage QA. Built for the languages machine transcription still fails on.

What Silencio AI powers

Voice agents

Conversational AI that works in any language your customers actually speak.

Robotics and wearables

Voice interaction that understands the world it operates in, not just the lab it was tested in.

Speech recognition

ASR that holds up across accents, dialects, and the acoustic conditions public datasets miss.

Low-resource language models

ASR, TTS, and conversational AI for the languages the internet still cannot hear.

Speech translation

Real-time translation between languages public data barely covers.

Accessibility

Hearing aids, captioning, and voice prosthetics that work in the languages users actually speak.

Voice biometrics

Identity and authentication trained on the demographic breadth these models need.

Voice cloning and TTS

Natural synthetic voices in the languages public corpora cannot teach.

The Contributors

Join 2.5 million people, paid to be heard

Every dataset starts with a real person on a real device, recording in their own language, in their own environment, on their own terms. Consent captured on-chain, anonymous in the dataset, paid in stablecoin. They are the reason voice AI can reach 180 countries.

Integrity

Auditable end to end, by design

Consent captured on-chain, immutable. IP-clean provenance from contributor to dataset. 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. Visual: stylized compliance stack, a consent receipt artifact, or a dataset card with provenance metadata exposed
