The languages currently available for download are the ones that last year were already launched and had validated hours before we started the dataset creation later last year (Basque or Spanish for example were not even launched by that time)
Dataset releases are really time consuming for the team and we are still trying to figure out how to be able to release them more often (I’ve added this as a todo on my list to discuss with the team).
You can say with confidence that Basque is fully launched on Common Voice, but that dataset are currently released not that often and you have just started collecting voices.
