Common Voice Legal Terms by Mozilla

Updated 10 December 2025

These are the legal terms governing participation in Mozilla's Common Voice project. They outline eligibility requirements, rules for contributing voice data and text, and how contributions are made available under a Creative Commons CC0 public domain dedication. The terms also cover account usage, disclaimers of liability, and the governing law for the agreement.

Common Voice Legal Terms

Effective [effective date]

As of the “Last Updated” date above, the information and datasets we make available through Common Voice will now be accessible through [company name] Data Collective (“MDC”).

Through Common Voice, you can donate your voice, written sentences, and the other resources we need to build an open-source voice database that anyone can use to make innovative voice recognition apps for devices and the web.

You may only participate in Common Voice if you agree to these Common Voice Legal Terms (the “Terms”). Your use of [company name] Common Voice is governed by these Terms and Common Voice Privacy Notice.

Eligibility

Common Voice is open to anyone over the age of 19. If you are 19 or under, you must have your parent or guardian’s consent and they must supervise your participation in Common Voice.

Common Voice is part of the [company name] Community. As a result, if you chose to participate, you agree to follow the [company name] Community Participation Guidelines.

Your Contributions

We make [company name]’s Common Voice dataset available under the Creative Commons CC0 public domain dedication. That means it’s public and we’ve waived all copyrights to the extent we can under the law. If you participate in Common Voice, we require that you do the same. You agree that [company name] may offer all of the contributions you make available to Common Voice, including text, recordings, validations, and feedback (the “Contributions”) to the public under the CC0 public domain dedication.

In order to participate in Common Voice, [company name] also requires that you make three assurances:

First, that your Contributions are entirely your own creation.

Second, that your Contributions do not infringe on any third parties’ rights.

Third, that your Contributions comply with [company name]’s Acceptable Use Policy.

If you cannot make these assurances, you may not participate in Common Voice.

In addition, if you participate in the Common Voices Spontaneous Speech project, you agree not to include any sensitive or personal data about yourself and others in the recordings you submit.

Lastly, [company name] makes the Common Voice datasets available to the general public exclusively through MDC under a Creative Common Zero (CC0) license, unless otherwise specified. Consistent with our data stewardship principles we ask that you not post, distribute, or mirror any Common Voice dataset, in whole or in part, on other platforms or services, and that access by others take place only through MDC.

Your Account

You do not have to create an account to participate in Common Voice.

To participate in some additional features in Common Voice (such as adding small or bulk sentence submissions, reviewing sentences, or adding or transcribing prompts), you will need to create a [company name] account. You can create a [company name] account here. Your use of [company name] accounts is governed by the [company name] Accounts Terms of Service and [company name] Accounts Privacy Notice. If you create an account, [company name] will ask for your email address and a username of your choice. Optionally you may also provide an avatar and certain demographic data through the Common Voice Platform. Demographic data helps us and other researchers improve and create speech-to-text technology and tools.

If you participate in the Alpha or Beta testing for the Common Voice Spontaneous Speech project, you must provide your email address so that we can send you a link to log in to participate in the Common Voice Spontaneous Speech project.

When you provide information for your [company name] account in connection with Common Voice, you give [company name] all permissions necessary to: keep track of information about your Contributions, associate those Contributions with your account, email, username, and the demographic information you provide, publish your Contributions publicly along with any demographic information, and publish metrics about your Contributions (such as number of recordings and languages) along with your username on the leaderboard.

[company name] will not publicly post or publish your email address.

You can choose not to appear on the leaderboards. If you do, [company name] will not publish data about your recordings in association with your username. However, [company name] will still make your text and recordings publicly available as part of Common Voice and will include information about your recordings in the overall metrics that are available publicly.

Communications

If you subscribe to receive our newsletters or register for a [company name] account in connection with Common Voice, you may receive emails from us in connection with your account.

Disclaimers

By participating in Common Voice, you agree that [company name] will not be liable in any way for any inability to use Common Voice or for any claim arising out of these terms. [company name] specifically disclaims the following:

Indirect, special, incidental, consequential, or exemplary damages, including without limitation direct or indirect damages for loss of goodwill, work stoppage, lost profits, loss of data, or computer malfunction.

Any liability of [company name] under these Terms is limited to $500.

Notices of Infringement

Updates

Every once in a while, [company name] may decide to update these Terms. We will post the updated Terms online.

If you continue to use Common Voice after we post updated Terms, you agree to accept that this constitutes your acceptance of such changes. We will post an effective date at the top of this page to make it clear when we made our most recent update.

Termination

[company name] can suspend or end anyone’s access to Common Voice at any time for any reason. If we decide to suspend or end your access, we will try to notify you by the email address associated with your account or the next time you attempt to access Common Voice.
