ABSTRACT:
A personal removable mouthpiece can be slipped over the mouthpiece of a voice amplification instrument. An aperture in the removable mouthpiece allows a user to use the voice amplification instrument without the user's mouth coming into contact with the instrument. When a second user begins using the instrument, the removable mouthpiece is replaced thereby preventing the second user from being exposed to any communicable disease of the first user. The removable mouthpiece includes inner and outer annular walls with an annular opening defined therebetween into which the mouthpiece of the voice amplification instrument is inserted. The inner and outer annular walls are connected at bottom ends thereof by a bottom annular wall.
