That's an interesting idea of letting players seamlessly be able to record voice overs for text they read, and let people quickly rank the best voice overs for particular dialogs on the workshop or somewhere. Unfortunately, 99% of people don't have the equipment or the voice skills to deliver high quality voice overs, so it'd probably be a flop for the most part. Voice overs are really hard, and it's easy to sound completely ridiculous or out of role or fail to enunciate correctly. Imagine having to curate all the garbage people record on their laptop mics. You'd probably get a handful of decent amateur voice actors and that's it, but maybe those handful of people could really flesh the game out.

Quality voice acting is nice, but good writing with lots of choices is better. And terrible voice acting is worse than having none at all. You're playing a cRPG, so expect to read. There really isn't even that much writing in D:OS.
