set_emote_voice list
 

Here is the list of the voices you can set your emote voice to using:
set_emote_voice xxxx
(where xxxx is the # of the race/voice you want to set it to).

I made an emote toolbar for my voice emotes with the Onpress function. I play an Iksar, but liked some of the other voice emotes better.

Ex: If I liked the Brute Male /cheer emote instead of Iksar (Cazic be praised? no thanks!), I would use the command:
OnPress="set_emote_voice 1004 ; cheer"

I'd had varying success with changing the voice back to Iksar Male 1 (1028) at the end. Eventually, I just left it off and set all emote buttons to set the voice at the start.

Note: You can only set your emote voice to whatever you're limited to by your race.
