Chapter 2.- The production of speech sounds

          

            I noticed that muscles are contracting when we speak. For that reason, is important to know the different parts of the vocal tract, so they are called articulators. Also, articulatory phonetics studies articulator. There are seven articulators such as lips, pharynx, soft palate, hard palate, tongue, teeth.  They are the main ones used in speech. Moreover, I saw the differences between vowels and consonants such as vocoids and contoids. Vocoids because there is not obstruction to air flow while Contoids there is. Besides, the distribution of vowels and consonant is different for each language as English cardinal vowels are located on a four side figure: from, back ,close, open.
