There are some. Like
this one. But it's mostly very amateur voice acting, which often makes me wish there wasn't any in the first place.
I thought about it before, but the costs of doing it right would be higher than what a VN can earn. For instance, Cinders has 450 pages of dialogue. Back at the company I worked for before going indie, we paid $500-$700 for just a few pages of professional voice acting. And that was very cheap, as we contacted the actors directly to skip the middle man and pulled some favors. Recording something like Cinders would be in tens of thousands.
Not to mention the logistics of it. Maintaining the quality of VO of such length, cutting it into lines, directing the actors, requesting re-recordings -- it would be a full time job. Also, once something is recorded, you can't change the text, as it would require another session. Which means we would have to do it only after the game is done and tested, pushing the release date by another few months.
All in all, it's completely beyond the reach of a small indie like us.
