||Jeremy Schaap, who was the announcer in the TCO 2007 video (of which a tiny bit was shown here) did a spectacularly great job. It demonstrates that he is complete professional in his line of work. Clearly as an outsider, he must have put in quite a bit of research to speak knowledgeably about the competition and clearly he had lots of help from insiders. Before the competition I did not expect that an outside commentator could do a believable job on such a specialized knowledge intensive event. But he completely exceeded the limits of my imagination. The TCO 2007 videos will be very difficult to match for quality. I don't know how much he got paid for the gig, but TopCoder sure got their money's worth from him.
In the snippet of the video here, Jeremy is pronouncing Jan_Kuipers' first name (as far as my untrained and dyslexic ear can tell) like the English word "yawn." I thought that was the right way (or as close as you could expect to get in English). Is there some problem with that? You could listen to the original video where he gets to say "Jan_Kuipers" many times if you really want to grade him on his pronunciation. The real embarrassing mispronunciation incident in TopCoder announcing history was a bit earlier in a different year and with a different champion, Petr. But I think the staff learned a big lesson that day and have been careful since.
