So I found this site, forvo.com, which is getting people all over the world to pronounce words in their native language. Pronunciations can then be rated so that bad pronunciations can be replaced by good ones.
They’re still getting started, so words in some (all?) languages are pretty scarce. I found that there is not a single word in Welsh (Cymraeg) that has been pronounced and I want to hear how the “ll” in Welsh is really pronounced!
Is anyone else interested? What languages can you help the site with? Have they missed a language?
