CHAPTER TWO - THE PRODUCTION OF SPEECH SOUNDS

         After seeing this video about the production of speech  sounds which are places of articulation and organs .

I learned the importance about them in order to produce the vowels and consonants sounds  because Vowels are sounds formed in the throat with the assistance of the tongue and mouth.It means that  vowels can be spoken alone.While consonants are formed by controlling the breath flow and shape of the mouth and tongue. It means that consonants cannot be spoken alone.Example :  a, bee, see, dee, e, ef, gee, ach. In conclusion,The difference between vowels and consonants is based on physiological: airflow ,acoustic: prominence and phonological: syllabicity.
