That is really well done. The only thing that gives it away (to my ears at least) is it's missing the trademark stutter/repeating words.

(Not hating on Rogan, just listen to any real clip and you'll see what I mean, e.g. https://www.youtube.com/watch?v=VvswhogSiY0)

EDIT: I listened longer and the AI actually is throwing in some "uhh"s and pauses. They don't sound completely naturally but it's still really impressive

I prefer this one, personally. https://www.youtube.com/watch?v=nhekF0ZF1Pk

Love that one, this bionicle discussion one is top tier as well: https://youtu.be/_eybyDddRk8

That's amazing. The writing reminds me of Aqua Teen Hunger Force

Here is another one: https://www.youtube.com/watch?v=xbxE_qODnKA

Aliens and Elon Musk, it's definetly on point with those two topics, a couple of Joe's favorites.

I would like a print of Altman's t-shirt.

It mimics everything incredibly well, except for curiosity ("?") and soul ("!"). Very much like print, soulless speech patterns persist through the entire interview, as if they were reading a screenplay. The hesitations and pauses are still there, but not the soul. So either AI translates English punctuation poorly, or they weren't picked-up enough times to mimic themselves into this interview. Example: "Abolutely, Joe!" is very flat and non-emotional. It is uttered as a louder sentence. https://www.youtube.com/watch?v=meu0CoYv3z8&t=460s

it was actually pretty good at adding some emotion here and there

i wonder if they have some extra input/coding to mark for inflections, etc

maybe they just tried a bunch of times and picked the best fit for the context

Train by day!
