Phonetics I – Fall 2010
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.
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
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
