The Notes column in the table at this URL: https://nwn.wiki/display/NWN1/Voicesets+or+Soundsets has "Player voiceset no extra lines." for the voicesets you can select during character creation. I loaded a Wailing Death saved game and tested every V key emote. All of the V key emotes had audio scripts associated with them.
During Arelith character creation If I select a voiceset that is from the vanilla game (Wailing Death), should all of the V key voice emotes have audio scripts available to them?
