The PC voices honestly sound like that have no personalty or flavor what so ever.
Looking back at BG1/2, each voice had a personality to it. The "evil witch voice" the "posh elf", the "dumb brute". In BG3 I can hardly tell them apart. It also appears that their voiced lines are all identical. Unless im mistaken. Some variety and flavor would be nice. Especially if you say, pick the "dumb brute" then your character lines in game, the rare time you to speak, are tailed to the voice and not all the same.
