From Noise to Voice
How the largest noise pollution databank became the voice data layer for AI.
Backed by the best
1,500 years of audio. Built before the voice AI data wall.
Silencio was founded in 2021 to build the world's largest noise pollution databank, with over 1,500 years of audio collected by a network of contributors across 180 countries. As voice AI hit the data wall in 2025, we pivoted the same network to capture voice and audio for the next generation of voice AI. Fortune 100 companies and frontier research labs now train their voice AI on data sourced from our network. The noise databank lives on at silenciosound.com.
