I listened to that yesterday, no one has replied yet.
I'm curious. I'm really not an expert on accents, but it's a strange one. It even seemed a kind of British accent at the beginning, but then it sounded more American. That accent confuses me!
Either it's a kind of pleasant and not strong British accent, or it is a strange American accent from I don't know where, or the speaker is not a native speaker of English, which might well be the answer...
Let's wait for the experts...
