Abstract: A vocalization appliance for assisting vocal cord closure training includes: an inner arc plate, an outer arc plate, and two partitions which are oppositely disposed, wherein the inner arc plate is opposite to the outer arc plate, and the two partitions are placed with an interval between the inner arc plate and the outer arc plate; the two partitions, the inner arc plate and the outer arc plate are enclosed to form an accommodating cavity, and the accommodating cavity is separated into an upper accommodating room and a lower accommodating room along a height direction; the upper accommodating room accommodates upper incisors while the lower accommodating room accommodates lower incisors; opposite side ends of the inner arc plate respectively extend away from the accommodating cavity, and opposite side ends of the outer arc plate also respectively extend away from the accommodating cavity, thereby separating mouth corners.

Abstract: An improved tongue depressor (10) that has a flat elongated blade (12) having a first end (14) and a second end (16). To the first end (14) is integrally attached a first tongue-contact section (34) and to the second end (16) is integrally attached a second tongue-contact section (70). Each of the tongue-contact sections has a lower surface (42) that includes sequentially, a downward slope (44), (80), a flat horizontal surface (48), (84) and an upper slope (52,88). The downward slope and the flat horizontal surface interface with the tongue and preferably have a non-slip surface (60). At the center and lower horizontal surface (20) of the elongated blade (12) is located a reinforcing protrusion (28) that prevents the tongue depressor from bending or breaking in the middle. Because the size of an adult mouth is generally larger than a child's mouth, one of the tongue-contact sections is made with a smaller width. Also, the tongue depressor is constructed of a plastic.
