6.1 Aspects of speech sounds

Speech sounds formed for the purpose of verbal
communication by the human vocal apparatus (the lungs; larynx

and vocal cords; pharynx; oral cavity with the tongue; lips; uvula;

and the nasal cavity). There are three aspects of speech sounds: the
articulatory, the acoustical, and the linguistic, or social.

Sometimes a fourth aspect, that of perception, is also
distinguished. There are many classifications of speech sounds,

based primarily on articulatory features. Though, one and the
same sound can be pronounced depending upon the accent.

6.2 Speech sounds as articulatory units and problem of their
classification

Articulatory phonetics deals with the categorization and

classification of the production features of speech sounds. A
thorough knowledge of how vowels and consonants are generated

remains essential for successful assessment and remediation of

articulatory and phonological disorders. Although contemporary
phonological theories have provided new ways of viewing

assessment and treatment of these disorders, knowledge of the

speech sounds’ production features secures a firm basis for
utilizing such procedures. Without this knowledge, phonological

process analysis, for example, is impossible.

6.3 The articulatory classification of the English vowels

Speech sounds are commonly divided into two groups:

vowels and consonants. Vowels are produced with a relatively
