Is it just me or is "AI" focused very much on fooling human perception, lately? AFAIK, we have no deterministic algorithm that can tell us whether synthetic language sounds "human", have we? So essentially, that model has been trained to fool human perception. Similarly, ChatGPT is not trained to output sensible and meaningful statements but rather statements that appear to be to a human reader. Would not not be time to measure a model's success on the actual job? Like feeding a simulator with actual data from real-world traffic scenarios and running Tesla's, or any other company's, autopilot in it?

It's a varied area of research, we do plenty of things. Training things on a simulator, and then using that to transfer domain to the real world is a fairly typical application.

AI is focused on creating electronic humans that are never tired and can do low skill work with some high level directions. It seems like we will achieve this goal, but the companies will own the electronic humans.

Perhaps it's us that are obsessed about perception rather than substance though? I wonder if it's different from asking a child to memorize for an exam, or investing time in a stylish presentation, etc. Seems like we're very often interested in something that looks like the job rather than the job itself - maybe because it's more easily measurable? We then took this skewed ambition and developed AI after it.

Do you seriously think that self driving car companies are not doing this already?

  > Is there any other sensible goal function for a text to speech model? Yes: to transfer information aurally. And the models are there, and have been for quite some time. They can simply stop with the trying-to-fool part.

    The "fooling here" is "people wanting TTS to sound human". And obvious step for that is making the AI infer human voice traits from existing humans

      It doesn't have to sound human. Fluent, ok, but human? But no matter what, it's unnecessary to make a tool that can copy anyone's voice. That just lowers the threshold for abuse, while not adding almost nothing of value.

        Listening to something that sounds non-human for a long period of time is fairly unpleasant; imagine trying to listen to an audiobook or podcast, or dialogue in an animated movie, when the voices are all obviously non-human/robotic. So TTS wouldn't be usable for a lot of cases where we might want it. And with the way the models work, once you have a model that can sound human, it is unfortunately very easy for it to sound like any individual human as well.

        It doesn't have to, and you can use ones that don't, they get the info across mostly. But it is jarring if it doesn't sound human, it's a speech impediment, or as a more generous take, an accent. The correct inflections, pauses, annunciations, etc. are all important to humans, especially so for audio books and similar things that need to immerse. Otherwise you have to strain to listen, similar to listening to someone with a heavy accent.
