Using AI is fine. It's a tool. And over half the people here bitching about "casting saves" are probably using an engine or some other tool that they didn't write to make their games, so screw that hypocrisy.
But in terms of the actual video, where the sampling begins, the voice is alright, but the delivery is flat. It doesn't carry any urgency. You might be able to screw around with some of the sentence structure and punctuation (i.e. "Can you HEAR what I'm saying?" instead of "Can you hearwhat I'm saying?").
