Use of AI voices moving forward

The feedback on the AI voices have been mostly negative.  While I personally like them and laugh at the mistakes they make, I appreciate that others don't feel the same.  On top of that, it seems many people turn off sound altogether in VNs in general.

Based on feedback, I think we have three options:  First we can turn the voices off by default.  There may be some users who hate the voices so much, they quit the game early and never come back.  Steam data suggests many users are not finishing the game.  This might help with that.  The downside is that if AI voices get turned off, real voices do too and the real voices are very awesome.

Second, we could keep the AI voices on by default, but notify the user at the beginning that they can be turned off.  There's already a warning in the beginning.  We could just expand the warning a bit more.

Lastly, we could produce an entirely new version of the game with only the real human voices. This would cover only a fraction of the dialog (as opposed to the 90% combined coverage with AI + Real), but this may be appealing to some users.

The AI voices could still possibly be improved.  There's some things I've been wanting to try like increasing model parameters or training longer on more focused datasets.  But there is considerable risk that no improvement may come from these experiments.
