You have to have PC voice in your interactions with other characters.
You don't.
This might be a generational thing; I grew up with protagonists that were usually limited with their lines (remember CDs?) and I hate voiced characters, and if they are voiced, I want them to be very, very barebones and easily modded (read: like BG1 and 2) because this allows me to have a voice made for the character. When my protagonist is (almost entirely) my dwarf can have a jamacan accent, I can have my elf or halfling sound like Barry White. When playing other games with voiced characters like Mass Effect, I can't imagine Shepard is originally from India, or Burhma, or Africa. Having Shepard voiced actually locks you out of roleplaying, constantly reminding you Shepard is from the american continent. This is completely ignoring the logistics involved and extra hard drive space all this would require. My point is, you might like having it but for me if the character's voice is preset, that's a Very Bad Thing; the first thing I do when making a custom character is imagine what they look like, and immediately after what they sound like. To me if your character is doomed with a preset voices you may as well junk the character creator entirely and have set characters; ie, play the preset characters like Gale or Wynn or Asterion, like you can in Divinity, though you can ofc customise their appearence too.
