AI should understand everyone.

The speech data infrastructure behind voice AI, built by the largest community recording speech: 2.5 million people in 185+ countries. First-party and consent-cleared. The one dataset you can’t scrape

ElevenLabs, frontier AI labs and Fortune 100 companies already train on our data.

Voice AI works well in a small fraction of the world’s 7,000 languages. For most of the rest, there is almost no recorded speech a model can learn from, and that gap cannot be scraped or synthesized. It has to be recorded by people, with their consent. That is what Silencio AI does. Our community records read speech and channel-split, multi-speaker conversations in their own languages and everyday environments. Our platform turns those recordings into off-the-shelf datasets, custom collection delivered in days, and native-speaker transcription, with documented consent and full traceability on every file. Voice is becoming how people talk to machines. We are building the data so it works in every language.VoiceAIworkswellinasmallfractionoftheworld’s7,000languages.Formostoftherest,thereisalmostnorecordedspeechamodelcanlearnfrom,andthatgapcannotbescrapedorsynthesized.Ithastoberecordedbypeople,withtheirconsent.ThatiswhatSilencioAIdoes.Ourcommunityrecordsreadspeechandchannel-split,multi-speakerconversationsintheirownlanguagesandeverydayenvironments.Ourplatformturnsthoserecordingsintooff-the-shelfdatasets,customcollectiondeliveredindays,andnative-speakertranscription,withdocumentedconsentandfulltraceabilityoneveryfile.Voiceisbecominghowpeopletalktomachines.Wearebuildingthedatasoitworksineverylanguage.

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.
