Listened to the video examples, sounded very good though wasn't terribly challenging text.

If only I could have that in Norwegian my SO would be pleased.

Also I totally misremembered regarding Kokoro TTS. It's good, but not what was butchering Norwegian. Forgot which one I was thinking of, maybe it was the old VITS stuff Rhaspy uses. Points stand, the voice was good but could barely understand what was said.
