Thanks everyone for the help. Luckily, when I was doing a solo duty there was a few "boss lines" and it was in fact the Voice Slider causing it. I had to lower it from 80 to about 20. I assume the last time I tried I didn't lower it enough.

This is a little weird cause all of the other voice lines during the talking cutscenes are perfect. I haven't tried the "Listening Position" slider. What I ended up doing was setting a macro button /voice 20 and just pressing the hotkey when I am in a duty.

Thanks everyone for the help!
