Forvo.com is a website where native speakers submit pronunciation of words.
The audio data is under the BY-NC-SA license.
I can't find any obvious place to download the whole data.
There is an API, but it only allows 500 requests/day, which means I would need 15 years to download the 2,740,170 pronunciations.
Where to download the whole data?
This is for use in an open source app from which I don't get any money, so my budget is zero.
