Obviously Persona 3 and 4 were made a long time ago and there isn't any indication of the main character not speaking yet, but I still feel like this is an interesting conversation to have. I've been rewatching the P4 Anime and that then encouraged me to pick up my late game save of Persona 3 FES that I didn't get through this summer. Swapping between the two is pretty jarring, but not for the obvious reasons of one being Persona 4 and one being Persona 3, or one being a game, and the other an anime. (The games never gives story through gameplay, so essentially one is just an uglier anime.) In the games you feel like a teenage ghost who someone pays attention to at the end of scene just to make sure you're awake. You're kind of just passively watching other characters have conversations you should be an active part in and you usually see them talk all, every, and which way around you. Since every girl in that group is your ride-or-die and every guy your best amigo due to S. Links, that doesn't feel right. A lot of that has to do with the poor dialogue trees (they're more like a dialogue sunflowers), a side effect of having a pretty linear story with no divergence. That's okay, they weren't (probably still aren't) trying to make a Mass Effect or a Walking Dead, but there's still a pretty easy way to get the player to feel more involved and make the story feel dynamic and more natural. A lot of this ignoring of the main character seems to come from his/her most obvious handicap; the lack of a voice for the others to interact with. Along with that, the fact that you don't have a set name. So, I'd propose the Mass Effect style of having a set voice and just having all the supporting characters call you by a last name that is preset. Say hello to Shepard-kun? Of course they could just have the entire name preset, too. I just feel like that would go a long way in distracting you from realizing how useless the dialogue sunflowers are and freeing the writers from being scared of having you play an actual part.
