Welcome to Mozilla Voice

Common Voice

The new home for machine-learning based voice technologies -- including software, tools, and datasets.

Voice technology should be available to everyone, in every language. We want to make it easy and affordable to deploy voice experiences through a set of comprehensive, commercially competitive, collaboratively built, open voice tools. Creating this set of tools will enable more businesses and forward-thinking developers around the globe to innovate by voice-enabling applications and/or devices without relying on Big Tech.

Get Started with Common Voice

Get Started

Mozilla Voice Developer Tools provide several key components of a full open source voice "stack". These components can be readily integrated with existing applications and platforms as well as suitable complementary technologies from other sources.

Mozilla Voice is built developer-first; giving you the APIs, documentation and tools to provide you with more choice in voice.

Our intention is that, over time, Mozilla Voice will become a feature rich voice technology platform.

Voice Mission

Mozilla Voice aims to contribute to a more diverse, decentralized, and innovative voice technology ecosystem through quality data, competitive, scalable, easy to use developer tools and inspiring products. In a world where voice experiences become the default way to interact with the internet and the technologies around us,

we want these voice experiences to be privacy-preserving, open, and accessible to everyone. Because competition and openness are healthy for innovation. Because under - resourced languages are an issue of access and equity. Because privacy and control matter. Especially over your voice.
