Ha! I Tried it with a couple names from my own language and it clearly is using an english TTS sound library. The pronounciation is better than you would get from a computer reading the name like an english word, but it's funny that even a language-neutral script such as IPA gets read with an english accent.

Accents can be (and many times are) specified in IPA scripts, so if the speaker carries an accent that isn't in the content he/she is reading or ignores any of the explicitly specified accents, then the pronunciation is wrong.

FWIW as well, linguists use different styles of IPA too, depending on the language families they most often work with.

Because of how it is used, IPA isn't really the 'one true standard' many would think it is.
