Organs of Speech The lungs are the source for producing a level of air pressure in creation of sound. 3

Organs of Speech Vocal cords: The air released by the lungs comes up through the wind-pipe and arrive at first to Larynx. The larynx contains two small bands of elastic tissue lying opposite each other across the air passage. These are called Vocal cords. When vocal cords are brought together tightly no air can pass through them. 4

Organs of Speech Larynx: is a complex structure of muscles located in the neck and partly visible in adult males. It is like a box where insight are glottis when the edge of vocal folds touch each other, the air can pass thorough the glottis. 5

Organs of Speech The pharynx: is a tube that begins above the larynx. It has been divided into two parts, one part being the back of the mouth and the other being the beginning of the way through the nasal cavity. 6

Organs of Speech Soft palate: is responsible to allow air to pass through the nose and through the mouth. It can be touched by the tongue when sounds K, G are made. 7

Organs of Speech Hard palate: is sometimes called the roof of the mouth; its smooth curved surface with the tongue like, t, d, sounds 8

Organs of Speech Alveolar ridge: is located between the top front teeth and the hart palate, Sounds made with the tongue touching is t and d. This is in contact with the other parts of articulators. 9

Organs of Speech Nasal cavity: is an area is near to soft palate that air resonates in the nasal cavities and passes it out through the nose as in the sounds of 'm' n' and ŋ/ng, ' 10

Organs of Speech Glottis: is a small tongue that makes a gap between vocal Cords when the air can pass through freely. As vocal vibrate the result vibration is produces voicing 11

Organs of Speech Teeth are usually composed upper and lower of the mouth. They play an important role in making sounds especially, tongue is in contact with upper side teeth for many sounds for example, sounds in / ð/ and /θ /. 12

Organs of Speech Tongue: as it is very crucial articulator it can be moved into many different places and different shapes, in can also be divided into different parts such as tip, blade, and front. 13

Organs of Speech Lips: are also important in speech sounds, they can be pressed together when they produce sounds P, V, B, f or rounded to produce vowels like U: Sounds in which the lips are in contact with each other are called bilabial while those with lip to teeth contact are called labiodental. 14

Organs of Speech Jaws: are being considered as articulator because of the movement of the jaws. 15
