Introduction to Phonetics
1. Branches of Phonetics
Phonetics is the branch of linguistics that studies the sounds of speech. Phonetics itself

• transcription: how speech sounds can be written down
• articulatory phonetics: how sounds are produced
• acoustic phonetics: the physical properties of sound waves produced in speech
