The surprising thing to some of us is how much it sounds like a human native speaker of that language speaking English. Not that it doesn't sound like 'native' English intonation, nobody would expect that, but still surprising to see how after being trained to speak language A, it sounds like a human language A speaker's accent when reading English too, even though that wasn't the training intent/setup. Perhaps not surprising to you that it would go like this because you understand the technology better so expected it! And then there are other people in this thread who disagree and don't think most of them sound very much like a human speaker of non-English language speaking English! So maybe it's not obvious after all...
