CV Project (originally released as Common Voice Android, later renamed CV Android) was an unofficial, open-source Android app for contributing to Mozilla Common Voice from a smartphone. Users could record sentences (Speak) and validate other people’s clips (Listen), even offline. It also added features the mobile website lacked, such as a daily goal with notifications, gestures, a dark theme, statistics and leaderboards, and it was translated into dozens of languages on Crowdin. Development stopped after version 2.5.1 in 2023, and the project was officially discontinued in July 2026.
Added a download progress bar and a “Clear offline data” button for Offline mode, plus an option to upload and download only on Wi-Fi. Includes 2.5.0.1–2.5.1 (up to 18 May 2023), which improved offline downloads, added options to swap the Yes/No buttons or require a long press in Listen, and fixed an Android 12 permissions bug.
Now requires Android 8.0 or later. Added badge, level-up and daily-goal notifications, accessibility improvements, push-to-talk (experimental), new gestures and a custom API server option. Includes 2.4.0.1–2.4.0.5 (up to 31 May 2022): translation updates and bug fixes, including one for Android 12 and later.
Renamed the app CV Project with a new icon, published it on the Amazon Appstore, and added text-size settings, in-app message banners, languages loaded from the server and optional ads in the Google Play version. Includes 2.3.1–2.3.9 (up to 1 September 2021), which added motivational sentences, playback speed control, customisable gestures and a configurable offline clip count. 2.3.9 was the last version for Android 6.0–7.1.
Added a daily-goal progress bar and sharing, an automatic theme, the option to turn off Offline mode, an in-app data reset, log export and native Android 11 support. The app also arrived on Huawei AppGallery. Includes 2.2.1–2.2.3 (up to 23 January 2021): language and offline-mode bug fixes and an F-Droid build fix.
Added login with a verification code, a splash screen, new badges, an improved Profile section and a validation-guidelines button in the first-run tutorial.
Rewritten from scratch with a new interface, Offline mode, Top contributors, app statistics, background sending of recordings and validations, and new animations. Includes 2.0.1–2.0.4 (up to 1 August 2020): the app was renamed CV Android, gained links to Mozilla’s Terms of Service and validation guidelines, fixed a crash in Listen and moved to the new commonvoice.mozilla.org domain.
Added optional gestures, a “skip recording confirmation” option and Persian. Includes 1.4.1–1.4.4 (up to 18 May 2020), which added Arabic and Catalan and kept Listen working after Mozilla changed its API response.
Released as 1.3.1: setting a daily goal now requires logging in and logging out resets it, with improved update checks, performance and translations.
Added a recording indicator sound, Check for updates, Report buttons, a “Record again” icon and a redesigned landscape layout. Includes 1.2.1–1.2.3 (up to 3 May 2020): bug fixes, translation updates and an updated anonymous statistics API.
Added the daily goal, new-version notices and a Turkish translation. 1.1.1 (23 April 2020) moved the app to the stable channel, with dialogs that follow the app theme.
Added the Speak section for recording sentences, a partial Dutch translation and anonymous statistics that can be turned off (beta, published as 1.0b).
Added a dark theme and faster clip loading in Listen. Includes 0.2.1b–0.2.11b (up to 13 April 2020): new translations (including Russian, German, Spanish and Czech), more supported languages, UI improvements and login fixes.
Added levels in Profile, an auto-play option for clips, today’s contributions and a reorganised Settings screen. 0.1.1b updated the Basque translation.
Early alpha and beta builds (0.0.1a–0.0.20b, up to 16 January 2020) that built the core app: clip validation, first-run tutorials, login, a Profile with badges, landscape mode and the first translations (Swedish, French and Basque).
