affricatives and voiceless plosives

State the difference between affricatives and voiceless plosives in English in terms of manner of production.


Affricative (âm tắc xát) : tʃ  dʒ

Voiceless plosive: p   t    k

Their differences:

Plosives (âm nổ, âm bật hơi): 

1. One articulator is moved against another so as to form a stricture that allows no air to escape from the vocal tract, the stricture is then total.

2. After this stricture had been formed and has been compressed behind it, it is released that is air is allowed to escape

3. If the air behind the stricture is still under pressure, when the plosive is released, it is probable that the escape of air will produce noise loud enough to be heard. This noise is called plosion.

Affricatives (âm tắc xát): 

1.The tongue tip touches the back part of the alveolar ridge, and the soft palate is raised so that the breath is trapped for a short time 

2. The rest of the tongue is in the [ʃ and ʒ ] position 

3. The tongue tip moves away from the alveolar ridge a little way and the whole tongue is in the the ʃ and ʒ so that short preiod friction is heard. The friction of [tʃ  dʒ ] is not so long as for [ʃ and ʒ ] alone./.
