ABSTRACT A vocal muffler for muffling the vocalization of a human, especially a crying baby. The muffler comprises a globe-like member having a chamber provided with a port positionable over the baby's mouth and via which the baby's crying enters the chamber to exit through muffled port means in bypassing relation to an inhalation port. A valve in the chamber opens the inhalation port during inhalation by the baby and closes the port in response to exhalation. The bypassing port means includes sound-attenuating means for muffling the baby's cries. The valve is contained loosely in a cage adjacent to the inhalation port so that when the muffler is not used as a muffler, the ball will rattle in the cage and the muffler serves as a toy rattle.
