The subject invention is a game call that is individually fitted to the user. One embodiment includes a molded plastic frame having an inverted "U" shaped channel in which a thermal plastic insert molded to fit the user's incisor teeth is retained. In a second embodiment, a thermal plastic strip is molded around part of the frame and is fitted between the user's incisor teeth and lip. The user may do the molding, which is carried out at relatively low temperatures. Adjoining either channel portion of the frame in the first embodiment, or the portion on which the molded strip is fitted in the second embodiment, is a planar arcuate shaped groove adapted to hold an elastic diaphragm. The call is held in the user's mouth with one surface of the diaphragm disposed adjacent the user's lip. As air is expelled from the user's mouth over the diaphragm, the user's lip modulates the airflow, thereby controlling the sound produced by the vibrating diaphragm. This call permits a person whose mouth or palate is too narrow to accommodate a conventional intra-oral diaphragm call, to produce equivalent sounds imitative of wild game, using a similar vibrating diaphragm that partially extends outside the mouth. The diaphragm may be removably mounted and may be changed by the user.
