Disable NusbieVoices.esp on your favourite mod manager. Use if upgrading Nusbie's Voices makes your Nusbie voices disappear. Put your crosshairs over an NPC, press the SexLab selection key (default N), and the option will appear under Mod Configuration > Sexlab > Voices and SFX. You can now set a voice for a specific NPC, or return it to random. The first is safer, but users have reported that deleting works without problems. Open the installed mod files (Data/Sounds/fx/Nusbie), play the audio files until you find the one you want to remove, and either copy a voice you do like over it or just delete it. Try clean saving Nusbie's Voices as explained below first, then SexLab if nothing else works. If that works, it's likely either this mod or SexLab itself wasn't upgraded correctly. Try starting a new game, wait until SexLab is installed, and check to see if the voices are in the Voices & SFX menu. You will at least want to disable Pigmy, the joke voice, but the rest depend on your taste. Wait for the message that voices have reset, then you can open Mod Configuration > Sexlab > Voices and SFX and deselect checkboxes for voices you don't want to hear. Load game and open Mod Configuration > SexLab > Rebuild and Clean > Reset Voice Registry. Install File with your favorite mod manager. Voices are English (or at least western) and have both moans and words.
