Phonetics and Phonology Is there any difference between phonetics and phonology ? If there is any difference , what is it? Many researches prove that both phonetics and phonology study the sounds of language , but each one deal with sounds in a different way. Phonetics deals with studying the sounds made by human voice when speaking , while phonology deals with how the sounds are combined to produce words and utterances. Because there is no single way or method to describe speech, Linguists explain the differences in many divisions. Phonetics is divided in three main branches: auditory phonetics, acoustics phonetics, and articulatory phonetics. The latter studies how speech sounds are produced or articulated in various parts of the mouth and throat. We make speech sounds when we modify the airflow passing through the mouth or nose by moving the tongue and other organs in and around the mouth. The muscles and organs that take part in producing sounds are called organs of speech. In articulatory phonetics, the phonetician describes how "Manner" & where "Place" the sound is made by the organs of speech. It is important to understand and distinguish between two major classes of sound: consonants and vowels. Consonants are pronounced by stopping the air from flowing freely through the mouth. Producing the sounds (/b/, /p/, /m/) requires stopping air completely by the two lips then released quickly. A vowel is a speech sound produced when air
