Legends ships with only one player voice available, female1. Installing voicepacks expands the list, giving you more choices and new voice playbacks, and adds more chatbind menu tree selections. If you are playing online and notice many chatbinds going by but you do not hear anything, and when you press the tilde key (~) and see errors locating voice files, you need these voicepacks.

[DA]Planeswalker created a chat .cs file (gives a new chatmenu option in the dropdown box in settings) that combines usage of available chatbinds from both of these packs across multiple voices, making use of .40's null voice capability.
