4. What is phonetics all about?

5. Three areas of phonetic science
articulatory phonetics
the production of speech sounds
acoustic phonetics
the physical properties of speech sounds
auditory phonetics
the perception of speech sounds

6. Articulatory phonetics
How are speech sounds produced? Which body parts are involved?
How do the organs involved in speech production work?
How do humans learn to produce speech sounds?

7. Acoustic phonetics What are the physical properties of speech sounds?
vowel

8. Auditory phonetics
Which body parts are involved in the perception of speech? How do they work?
How do humans learn to perceive speech?
How many words are produced?
