How do you do the voices?

Most of the voices are performed by myself into a microphone, then processed through an AI voice clone created using audio from the source material.

I do not rep any specific software, but if you're interested in trying this out, searching "AI voice to voice" will come up with some options. 

Did you hire the real Hotel Mario voice actors?

No, I might occasionally hire VAs for certain parts, but I enjoy performing most of the characters myself. If a VA is not listed in the video description, it's safe to assume it's me doing the voice using a clone.

Is it wrong to use other people's voice recordings this way?

Ethically, it's not really any different from splicing together the cutscene sprites or sentence-mixing, which people have been doing for years.

Why do you use AI?

SHORT ANSWER: I think it's funny and neat and it's fully my decision.

LONG ANSWER: Computers are magical devices that let us multiply our productivity. Used effectively they can allow a single person to match the output of a large team. They can even be used to create all new types of art that have never been seen before. All of this has been increasingly true throughout my life.

I disagree with people's attempts to draw a distinction between "AI" and any other computer application. When I open Photoshop and click "Render Clouds" to draw some clouds on the screen, I don't get Cloud Artists in my inbox calling me a hack. The anti-AI sentiment is going to die out the same way, as people start to realize the value of software comes from what humans do with it.

So it's just low-effort slop, huh?

It's certainly within your rights to make this rude conclusion about my art. As the person who spends hours and hours writing scripts, recording voices, and hand-drawing animation frames - all in order to make content that hopefully puts a smile on someone's face - I would certainly object to it. 

But it's not "art", you used AI.

There are a lot of misconceptions about what people can do with AI, and how it is typically used in productions. I've found the people who are least familiar with these workflows are the people who are most confident in making wild assumptions about them. I'm making animated online videos in the most classical possible sense, with tools that have existed for decades and methodology that takes years to master. AI is a small, subtle, integrated part of my workflow. All this to say: very rarely do the people who try to point at something and say "this isn't art" end up on the right side of history.

You should go back to sentence mixing instead.

I'm going to keep this one in my back pocket, just in case I ever decide I want the voices to take 10x longer, be less fun to do, and sound worse.

AI will take people's jobs away!

That really sucks, this is the first I'm hearing about it. My first thought is that we should probably do something about the billionaires who currently hoard this technology for profit when it could potentially be used to end all human suffering instead. But I'm just spitballing here.

You are reusing other people's work! WITHOUT THEIR PERMISSION!

Yeah, me and Tupac.

I don't like the video. Because of the AI

I get it! God, do you people have an off button?!
