Donate your voice: CV Project

Donate your voice: CV Project is a science & education application developed by Saverio Morelli, packaged as a single Android APK of version 2.5 weighing in at 7.96 MB. The package targets Android 4.1+ and above. Below you'll find the publisher's own description, a quick spec sheet, and a short buyer-beware checklist so you know exactly what you're installing before tapping download.

1. Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
2. File size is a light 7.96 MB, so it installs quickly even on modest connections.
3. This build is signed by "Saverio Morelli" — always verify the developer name matches what's listed on the app's official store page before installing an update.
4. After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
5. We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

What is the Common Voice project?

Common Voice is Mozilla's initiative to help teach machines how real people speak.
Voice is natural, voice is human. That’s why we’re excited about creating usable voice technology for our machines. But to create voice systems, developers need an extremely large amount of voice data.
Most of the data used by large companies isn’t available to the majority of people. We think that stifles innovation. So we’ve launched Common Voice, a project to help make voice recognition open and accessible to everyone.
Now you can donate your voice to help us build an open-source voice database that anyone can use to make innovative apps for devices and the web. Read a sentence to help machines learn how real people speak. Check the work of other contributors to improve the quality. It’s that simple!
You can find more details on the official website https://commonvoice.mozilla.org/

Why should you use the app instead of the website on mobile?

The app is developed specifically for smartphones so it's native. It has many features that website don't provide you, such as dark theme, offline mode, customisation, gestures, etc.
The app is lighter than website, without annoying animations (and animations in the app can also be stopped in Settings).
In addition, the website has many bugs, especially for mobile-version, so you cannot do everything correctly.

Is Donate your voice: CV Project free to download?
Yes. The APK file linked from this page is free. The developer may offer in-app purchases once installed, but obtaining the installer itself costs nothing.

What Android version does Donate your voice: CV Project require?
Android 4.1+ or newer. Installing on older devices may cause crashes or refuse to install.

Is Donate your voice: CV Project safe to install?
We link to the exact APK published by Saverio Morelli. We do not modify the file. Still, as with any sideloaded app, scan it with a reputable antivirus before opening it, and only grant permissions the app genuinely needs.

How do I update Donate your voice: CV Project?
Install the newer version on top of the old one — Android will keep your data. If the signature differs, uninstall first (you may lose local progress).

Why is the app not installing?
Common causes: not enough storage, an older Android version than 4.1+, or a conflicting build already installed. Free up space, check your OS version, and uninstall any previous copy before retrying.

1. Tap the Download APK button above and save the file to your device.
2. Open your device Settings → Security (or Apps → Special access → Install unknown apps) and allow your file manager or browser to install unknown apps for this one file only.
3. Open the downloaded org.commonvoice.saverio.apk file from your Downloads folder.
4. Tap Install and wait for Android to finish.
5. Open «Donate your voice: CV Project» by Saverio Morelli and grant only the permissions it actually needs.
6. Revoke the "unknown sources" permission once you are done installing.
