Preliminary Perspective
•An Affricate is sound is, under a
preliminary perspective, are a non-stop
combination of sounds begun by a plosive
(total stop of air causing an explotion)
sound and immediatelt followed by a
fricative (friction) sound.

Affricate Sounds of English
•There are two affricate sounds in english.

4. Phonetics I – Fall 2010
•In this affricate sound, the first sound is / t /
•This sound is produced with the tip of the tongue
placed in the alveolar ridge,
•The air flow is obstructed and the released,
WITHOUT making the vocal fold vibrate.
•Immediately, the second sound is produced

5. Phonetics I – Fall 2010
•The second sound is
•This sound is produced with the tip of the tongue
in the post-alveolar region (a little behind the
alveolar ridge).
•The air is let loose producing a hissing sound -It
produces friction.
•The vocal folds don’t vibrate either.

Further Discussion
•Peter Roach in his book English phonetics and
phonology: a practical course (Cambridge, 3rd
edition, 2009) points out that not all the combination of
plosive+fricative sounds are considered Affricate Sounds
.
•It is said that these type of combinations need to be
HOMORGANIC , that means, they must be produced
with the same articulators.
•In this way the combination / ks / of the word taxi is not
considered an affricate because the sounds are not
prouced with the same articulators
