Dure the pronunciation of the b and the p are fairly similar. That does not mean that the pronunciation is completely off. Either way I hear buurt.
*Its (there is no voice actor, just a program)
*pronunciation (only the verb has "ou" in it)
P seems to have less aspiration than the equivalent sound has in English, thus making it perhaps sound a little like a b to us.
It's supposed to be /b/, not /p/, so the aspiration of /p/ in English is irrelevant. Dutch consonants have no aspiration, and English speakers have no trouble distinguishing between /b/ and unaspirated /p/, although we think aspirated [pʰ] and unaspirated [p] are the same sound. And I agree with Thomas Myrman, it does sound like /p/ and not /b/ in "buurt" in this sentence.
