Can't really remember clearly (and definitely isn't in the mood of looking through everything right now), I think it was mentioned somewhere that Entoma picked one out of several voice types for Ainz to use when he's masquerading as Momon. There's at least two or three to spare, I think. Also, I can't remember when Ainz actually started using a lip bug when acting as Momon. Possibly after the little demon invasion because he was wary that Gazef might recognize his voice back then.

The people of E-Rantel never heard Ainz's voice before he arrived in the city in his undead glory, so Nurunuru may be specifically selected for when he's addressing the people as King. It's possible that Momon's lip bug is with Pandora's Actor so that his voice doesn't sound different from the usual Momon.
