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
