2 The production of any speech sound involves the movement of an air stream. The production of any speech sound involves the movement of an air stream. Most speech sounds are produced by pushing the air out of the lungs through the mouth (oral) and sometimes through the nose (nasal). Most speech sounds are produced by pushing the air out of the lungs through the mouth (oral) and sometimes through the nose (nasal).

3 Vocal Tract The airway used in the production of speech, especially the passage above the larynx, including the pharynx, mouth, and nasal cavities.

4 Articulators are divided into 2 parts: Upper articulators Lower articulators Passive articulators active articulators

5 1. Pharynx It serves primarily as a tube connecting the larynx with the oral and nasal cavities.

6 (Hard ) Palate Also called the roof of the mouth It is a curved surfaced.

7 Velum/ Soft Palate It is located between the pharynx and the hard palate. It controls the airflow into the nasal cavity. /g/, /k/, / ŋ/

8 Unlike he hard palate, which is made of bone, the soft palate is made of muscle and soft tissue. Unlike he hard palate, which is made of bone, the soft palate is made of muscle and soft tissue. When it is lowered it allows air to flow into the nasal cavity and exit through the nose. When it is raised the air can enter the oral cavity only. When it is lowered it allows air to flow into the nasal cavity and exit through the nose. When it is raised the air can enter the oral cavity only.

9 Alveolar ridge It is situated between the teeth and the hard palate. It is covered with little ridges /d/, /t/,/n/

10 The Tongue It is the most important articulator. It can be moved to many different places. It is divided into 6 parts.

11 The teeth They are located at the front of the mouth immediately behind the lips For many speech sounds the tongue is in contact with the upper teeth. /θ/, /ð/

12 The lips They are very important in speech The can be pressed together /b/, /p/, (/m/)

13 They can be brought into contact with the teeth /f/, /v/
