Acoustics
– the study of the physical properties of sound. 
Acoustic Phonetics
– science which studies the way in which the air vibrates between the 
speaker’s mouth and the listener’s ear, in other words, the sound wave. It is concerned with the 
physical properties of speech sounds and uses special technologies to measure speech signals. 
Affricates
– noise consonants produced with a complete obstruction which is slowly 
released and the air stream escapes from the mouth with some friction; an affricate starts as a 
plosive, but instead of ending with plosion, ends with a fricative made in the same place. English /ʧ, 
ʤ/ are affricates. 
Allophones
– variants of a phoneme, usually occur in different positions in the word, cannot 
contrast with each other and are not used to differentiate the meaning. Allophones of a certain 
phoneme are speech sounds which are realizations of one and the same phoneme and which 
therefore, cannot distinguish words. 
Allophonic variation of phonemes
– variation which is conditioned by phonetic position 
and phonetic environment. 
Alveolar
– a place of articulation where the tongue touches the ridge just behind the upper 
front teeth. An articulation involving the tip or blade of the tongue and the alveolar ridge, as in 
English /d/ in 
die
. /t, d, s, z/ are alveolar. 
Alveolar-palatal
– post-alveolar consonant made with considerable raising of the front of 
the tongue, making it equivalent to a palatalized palato-alveolar. 
Ambisyllabic
– belonging to two syllables. A consonant such as [p] in 
happy
is sometimes 
said to be ambisyllabic. 
American English
– the national variant of the English language spoken in the USA. 
Amplitude
– the distance to which the air particles are displaced from their position of rest 
by the application of some external force; the amount of energy present in a sound wave at a
