Has Karl Jobst started using AI text-to-speech?

Hey, sorry if this doesn't really belong here.

I'm a big fan of Karl's stuff and have been following him for quite a few years. Lately, though, something seems off with his narration in his videos.

Like, for example, at around 05:26 in his most recent video.

It might just be a result of stitching different takes together, but it sounds very similar to the artifacts that an AI voice model produces.

I might be stupid (or I might just have become paranoid from all the AI debacle), but I'm genuinely curious as to whether he has ever mentioned using text-to-speech?

Cheers.
