........................(3), whose protruding front is known as the...................................(4), the

.............—......—...........(5) are found. When they vibrate, sounds which are produced are

............—.......When they are.............................., the sounds are voiceless. The opening

between the.................

(5) is called the........................ When the stream of air

(3), it enters the cavity formed between the

..........(8) of the tongue and the back wali of the throat. This cavity is known as the

.........................(3). At the top of the throat, there is a forking of the air passage: the air

can pass out through the.................................................(11) or through the

called the...................................When it is raised, the way to the....................................

(11) is blocked and the air escapes through the.................................................(20). When

it is lowered, the air may go out through the................................................(11). In the

former case,.................sounds are produced, in the latter,................sounds. At the lower

end of the.......................(10) there is a smali movabie appendage that is known as the

.................(9). Both the..................(10) and the....................(9) are parts of the

.......................also called tbe roof of the mouth. At the front of the mouth the bony

structure forms the........................................(12). In the foremost part of it, just behind

the upper.......................(13), there is a prominent ridge known as the

.......................................(13). The major speech organ in the mouth is the

...........................Phonctically speaking, its surface is usually divided into the

...................................(16), the................................(17), the________________________(18)

and the.........................................(19). Finally, speech sounds may be modified by the

sbape of the ....................... (14).
