Common Voice
open-in-new
<p>Common Voice is a <a href="/facts/Crowdsourcing/pIjlvb3E">crowdsourcing</a> project started by <a href="/facts/Mozilla/FevL9Itn">Mozilla</a> to create a free <a href="/facts/Database/VYcpkevb">database</a> for <a href="/facts/Speech_recognition_software/z7S7Pgk6">speech recognition software</a>. The project is supported by <a href="/facts/Volunteer/U0V4Nj1z">volunteers</a> who record sample sentences with a <a href="/facts/Microphone/7YWGlXCl">microphone</a> and review recordings of other users. The transcribed sentences are collected in a voice database available under the <a href="/facts/Public_domain/YWKMDKw4">public domain</a> license <a href="/facts/CC0/6AV3V7UJ">CC0</a>. This license ensures that <a href="/facts/Software_developer/WGTS1Jv9">developers</a> can use the database for voice-to-text applications without restrictions or costs. </p>
