💎 Open Speech Corpora

A list of open speech corpora for Speech Technology research and development.

This list has a preference for free (i.e. no $ cost) and truly open corpora (e.g. released under a Creative Commons license or a Community Data License Agreement). Not all these corpora may meet those criteria, but all the following corpora are accessible and usable for research and/or commercial use.

Feel free to propse additions to the list!

There's a long backlog of corpora to be added in the Issues, and Pull Requests are very welcome :)
