[RPG] ny spell that alters the voice


In my next session, the villain will disguise himself as a plague doctor and will be with the players for some time.
The mask will hide his identity and in any case he can disguise himself but, one of the players, however, knows his voice.
The mask can also alter his voice to some extent but I wanted to make sure his voice sounded different, is there any spell that allows that?

You transform your appearance. You decide what you look like, including your height, weight, facial features, sound of your voice, hair length, coloration, and distinguishing characteristics, if any,... (PHB 212, emphasis mine)
