Common Voice: crowdsourced multilingual speech

Posted 16 Oct 2026

Volunteers record themselves reading short sentences, and other volunteers validate the clips. Each clip has a transcript and optional speaker details such as age range and accent. It is a key resource for speech recognition in languages with little other data.
