. All the sounds we make when we speak are the result of muscles contracting
What is the relation between the air coming from the lungs and the place of articulation?
The muscles in the chest that we use for breathing produce the flow of air that is needed for almost all speech sounds; muscles in the larynx produce many different modifications in the flow of air from the chest to the mouth.
المناقشة 2:
The first point at which the flow of air can be modified, as it passes from the lungs, is the larynx(you can feel the front of this, the Adam’s apple, protruding slightly at the front of your throat),, in which are located the vocal folds (or focal cords). How can the vocal folds play role in determining whether the sound is voiceless or voiced ?
a.The vocal folds may lie open, in which case the airstream passes through them unimpeded. Sounds which are made when the focal folds are open are called voiceless sounds. Thus, /s/ is a voiceless sound
b.The focal folds may be brought together so that they are closed, and no air may flow through them from the lungs. When the air comes from the lungs, the build up of air pressure underneath this closure is sufficient to force that closure open, but the air pressure then drops, and the muscular pressure causes the folds to close again. The sequence is then repeated very rapidly and the results in what is called vocal folds vibration this vibration is felt when you put your fingers to your larynx and produce a sound like /z/. Sounds which are produced with this vocal folds vibration are said to be voiced sounds, whereas sounds produced without such vibration are said to be voiceless.
المناقشة 3 :
What is the difference between place of articulations and manner of articulations?
The place of articulators consonant is the point of contact where an obstruction occurs in the vocal tract between an articulatory some part of the roof of the mouth along with manner of articulation and phonation this gives the consonant its distinctive sound
المناقشة 4:
What is Affricates?
That friction occurs during the release phase of the closure. Sounds produced with a constriction of complete closure followed by a release phase in which friction occurs are called affricates. These are: / ʤ/ /tʃ/
المناقشة 5:
What is the different between aspirated & unaspirated?
-The first stop in pit, we said, is a voiceless bilabial stop. So too is the first stop in spit. But the bilabial stop in pit differs phonetically from the bilabial stop in spit: if you hold the palm of your hand up close to your mouth when uttering pit, you will feel a stronger puff of air on releasing the bilabial stop than you will when you utter spit. That stronger puff of air phenomenon is called aspiration: we say that the bilabial stop in pit is an aspirated voiceless stop, whereas the stop in spit is unaspirated.
