I've watched some chess grandmaster speed chess games. The streams were okay. Many players don't make much of effort to enunciate clearly. It sounds like they're got a gobstopper in their mouth. And they don't usually bother to explain much either... "Why didn't I move the knight to b3?" Yeah, why? I looked really good to me. Gnomic utterance: "There were obvious tactical limitations." Ah, yes. Obvious.
