AI voices for audiobooks – but can it do a bad joke?

Saw the ebook-to-audiobook tool with 'realistic' AI voices. I've been doing stand-up long enough to know timing is everything – a beat of silence before the punchline can make or break it. A voice that never hesitates might technically sound human, but it misses the stumbles and pauses that make speech feel alive. Not saying it's useless for narration, but I wonder if anyone's thrown a poorly-timed joke at it yet.
