That is different from person to person. As long as it's not overpowering the voice it should be ok for most.
Many preffer to be able to set the reading speed though (2x and 3x not uncommon) and to be able to skip to the important part of the message. Especially important when you can't use visual pattern scanning on text that shows up often.
Mabe use the browser to create a textbased game? The tools exists there already and the users are used to use them.
I’m especially interested in creating a 3D soundscape, maybe something similar to what is described here: https://www.gamasutra.com/view/feature/131900/playing_by_ear... but not necessarily instead of text, but rather to augment it. Based on what you’re saying, it would probably work well enough: have separate volume controls for music, ambient sound and sound effects (as most games have already anyway — many games have a voice volume too, but I guess voice should be left wholly up to the screen reader and it should control the volume/speed).
Using a browser sounds like a good idea. Definitely wouldn’t want to implement screen reading capability yourself!
