I think it sounds pretty good, but reserve judgment until seeing it with visuals which I know you say is coming. Din does sound like he has slipped an ambien sometimes, but I just think that is how his character comes across especially with a modulated voice. I think it is just more apparent in this monologue because normally he is a man of few words so such a long speech may take a little getting use to.
Wish AI could be given some prompt to put more inflection into the voice based on mood. However, I am still in awe of how far the tech has come in just a year. Really looking forward to this final book. Thanks for putting in all the hard work acbagel.
