Document Summary
Allomorphy often depends upon phonetic properties of morphemes; and rules defining the possible sound structures the language permits. To explain those fully, we have to know how to describe speech sounds. Most speech sounds are produced by air from the lungs passing through the vocal tract; the positions of the organs in the vocal tract determines the sound the air makes. If vocal folds are held partially open, they vibrate as air passes over them; Example: v and z are voiced speech sounds; f and s are voiceless: If the airsteam encounters no significant obstacles between larynx and lips i. e. , the air flows freely through the vocal tract the sound produced is a vowel. the resulting sound is a consonant. If there is some blockage in the vocal tract that air must go through or around, Consonants are described in terms of two main parameters: These parameters plus voicing let us classify all the consonants used in english.
