2. CHAPTER 2 THE PRODUCTION OF SPEECH SOUNDS

We have a large and complex set of muscles that are use to produce sound when we speak. Basically, the articulators in the vocal tract are: pharynx, soft palate, hard palate, alveolar ridge, tongue, teeth and lips. According this site"http://http://en.wikipedia.org/wiki/Articulatory_phonetics#Places_of_articulation" Movement of the tongue and lips can create constrictions and by forming the oral cavity in different ways, different sounds can be produced.Sounds of all languages fall under two categories: Consonants and Vowels. The main difference between them is a differnce in the way they are produced as for example the shape of position of the tongue.At the end of this chapter we can say that all all parts into the vocaltract helps us to speech.
