Made by passionate people like you

At Mozilla, we’re a global community of technologists, thinkers, and builders working together to keep the Internet alive and accessible, so people worldwide can be informed contributors and creators of the Web.

Our voice technology, datasets and tools, are created in the open and build so they can be used, remixed, and advanced by everyone.

The constant support and feedback we get from contributors, testers, technologists, and researchers that form our diverse communities is essential to the work we do and the way we do it.

You can be part of them and help us and others build better voice technology for the benefit of all.

Common Voice

As a community-driven project, people around the world who care about having a voice dataset in their language have been responsible for each new language launch — some are passionate volunteers, some are doing this as part of their day jobs as linguists, data scientists or technologists. Each launch requires translating the website to allow contributions and adding sentences to be read.

Mozilla Voice STT & TTS

Mozilla Voice STT & TTS Licensed under the Mozilla Public License, Mozilla Voice STT and Mozilla Voice TTS can be used for commercial and/or non-commercial purposes, and, from the first commit, both were developed in the open for the good of the community. In fact this community has given back much more than we could have ever expected. Over 95% percent of the contributors are external to Mozilla! So both Mozilla Voice STT and Mozilla Voice TTS are truly for and products of the open voice tech community.

Get Involved

We believe the world needs open alternatives to existing commercial offerings: Voice technology should be available to everyone, in every language.

From growing our open datasets as a voice contributor or optimising their quality as a data scientist to advancing our developer toolkit and building applications on top of it: your skills and passion matter to make voice technology accessible to everyone!

A good overview of the different contribution areas and the roles you can take up is described in our Mozilla Voice Community Playbook.
