I personally would like to contribute towards the Odia language. There was a project that I started last year to grow more recorded words, and there are 2000+ words that can be uploaded if there is an option. But Odia Wikipedia and Wikisource are also great source for CC-BY-SA, Public Domain and CC-BY licensed text that can be used.
I have another question. I see a lot of cross-open source project collaborations here. Maybe you can think of this as well. If someone records a Wikipedia article, there should be an option to download the same and upload it on Commons, Wikipedia’s sister project, so that the recorded version can be used for Wikipedia when it is used here on Common Voice. It will be a win-win situation for both the communities (Mozilla and Wikimedia).
