1. phonetics: the study of how speech sounds are produced, transmitted, and perceived. It can be divided into three main areas of study—articulatory phonetics, acoustic phonetics and perceptual/auditory phonetics. articulatory phonetics: the study of the production of speech sounds, or the study of how speech sounds are produced/made. phonology: the study of the sound patterns and sound systems of languages. It aims to discover the principles that govern the way sounds are organized in languages, and to explain the variations that occur. speech organs: those parts of the human body involved in the production of speech, also known as ‘vocal organs’. voicing: the vibration of the vocal folds. When the vocal folds are close together, the airstream causes them to vibrate against each other and the resultant sound is said to be ‘voiced’. When the vocal folds are apart and the air can pass through easily, the sound produced is said to be ‘voiceless’. International Phonetic Alphabet: a set of standard phonetic symbols in the form of a chart (the IPA chart), designed by the International Phonetic Association since 1888. It has been revised from time to time to include new discoveries and changes in phonetic theory and practice. The latest version has been revised in 1993 and updated in 1996. consonant: a major category of sound segments, produced by a closure in the vocal tract, or by a narrowing which is so marked that air cannot escape without producing audible friction. vowel: a major category of sound segments, produced without obstruction of the vocal tract so that air escapes in a relatively unimpeded way through the mouth or the nose. manner of articulation: ways in which articulation of consonants can be accomplished—(a) the articulators may close off the oral tract for an instant or a relatively long period; (b) they may narrow the space considerably; or (c) they may simply modify the shape of the tract by approaching each other. place of articulation: the point wh
