World of Warcraft: The Next Step
From the standpoint of role players, however, it has a serious disadvantage. It's hard to believe that the person you are talking with is a female elf when "her" voice is that of a young man. It's hard to believe in the elderly dwarf when the voice is that of a sixteen year old girl. And it's hard to hear the frivolous and irresponsible gnome in the voice of a sixty-some professor.
This problem is soluble. There exist ways of modifying the sound of a voice--shifting the frequency up or down, changing it in subtler ways. Blizzard should make them available as an option on its in-game speech. Players who want to sound like themselves can, but so can players who want so sound like their character—deeper voices for males, still deeper for dwarves, and whatever tones feel right for other races. With a little practice, it ought to be possible for the speaker to learn to control the modified voice well enough to express emotions in a believable fashion, and so to carry in-game role playing to a new level.
