Naming things is, of course, the hardest part of programming so somewhat hypocritically I can't say I have an answer :) . It probably depends more on what you view your target audience as and what your main selling point is. Discord worked as a name since it falls in line with a lot "gamer branding". If you have a theme going on I'd go with that, otherwise the age old traditions of picking a random communication related or mashing two words together (Linphone, Threema, Skype, etc) are probably the easiest.
Personally I think I'd go with "Microcosm" or something similar. Sounds cool, abbreviates well to just "micro". Or maybe something with "vox" in it. Honestly it probably doesn't matter too much, people will get used to saying anything.
