“The Science Of Speech”

Phonetics is the area of the language that mainly looks at 3 things:
1-How we physically (or physiologically) produce sounds. (Articulatory Phonetics)
2-How we analyze the sound transmissions and patterns including the conditions in which they are produced. (Acoustic Phonetics)
3-How our ears, auditory system and brain filter and process these sounds once they receive them. (Auditory Phonetics)
