Donate and validate our voices under licence to generate a dataset usable by Speech to Text technologies to train models in different languages democratizing voice technology.
We are a community of voice tech enthusiasts, who want to help collect and generate a large dataset of public domain voices that can be freely used to train .
Collect and validate as many voices as possible in our languages. Having more voices validated allows us to then train more advanced STT models.
At least 1,000 unique speakers per language.
2,000 hours of voice validated to train a near-human general STT model.
10,000 hours of voice validated for a very high quality, general, large vocabulary, continuous speech recognition model.
🔨 You don’t need any specialized skill to contribute to this community, you only need to be able to speak into a microphone or listen to audio clips.
⚠️ In order to have a language enabled on our site, you will need at least 5000 validated sentences, see previous section about text corpus for reference.
Voice donation
Feel free to create an account to track your progress and add more information on your profile about your voice. Demographic information helps us balance the dataset, giving machine learning researchers and engineers a way to train models that represent better the speakers of the language.
⚠️ Note: Once you have recorded a decent amount of clips in your language (around 300), it’s more valuable for less effort if you jump into helping to get new voices from other people and focus on the voice validation part, this will increase the dataset quality.

The complete text and voice dataset for languages where we have data is currently generated by the Common Voice staff team.
ℹ️ Note that we are asking for an email to send the link to the dataset (instead of direct download) because we want to have a way to contact everyone who downloaded the data in case we get deletion requests from contributors.
We understand that some people might want more frequent releases, and we are working on a more continuous release model to accommodate these needs.
These are some roles you can take as part of this community.

We have developed a site that allows you to by reading sentences collected by the community.
ℹ️ to know how to produce better voice donations.
The same site allows you to by listening to voices donated by the community. Each recording will need at least two positive validations from different people. Feel free to create an account to track your progress, compare with other contributors, set yourself goals or get awards badges.
