Large-scale Abkhaz voice data collection campaign on Mozilla Common Voice

As of December 2025, the Abkhaz language dataset on the Mozilla Common Voice platform contained 104 hours of recorded speech, with a 65% validation rate. At that stage, 426 participants had contributed recordings. Starting in December 2025, by agreement with the Ministry of Education of the Republic of Abkhazia and with the participation of Abkhaz State University, the Shinkuba Abkhaz Language Development Foundation launched a large-scale campaign to expand the Abkhaz speech dataset on the Common Voice platform. During this period, specialists of the Foundation organized recording sessions across multiple regions of Abkhazia. Participants included students and professors of the university, high school students, school teachers, and volunteers from different age groups. As a result of this campaign, more than 150 additional hours of speech recordings were collected. By early March 2026, the Abkhaz dataset on Mozilla Common Voice reached a total of 254 hours of recorded speech, with 86% of the recordings validated. More than 800 new contributors participated in the campaign during this period.

The campaign involved numerous educational institutions throughout Abkhazia.

Abkhaz State University also played a major role in the project. Recording sessions initially started at the Faculty of Philology and later expanded to other faculties, involving approximately 200 students and professors.

Scale of public participation

Overall, more than 800 new contributors joined the project during this stage of data collection. Considering the size of the Abkhaz population, the campaign reached a remarkable level of public participation: more than 1% of the Abkhaz population contributed their voices to the dataset. Such a level of public engagement in building a speech dataset is extremely rare and represents a remarkable example of community participation in the digital development of a minority language.

Documentation and public outreach

All recording sessions were documented through photo and video coverage. The project team recorded each school visit and community event where speech recordings were collected. Project updates and documentation can be found on the Foundation’s public channels:
