Phonetics : The Sounds of Language The science of phonetics attempts to describe all of the sounds used in all languages of the world. Knowing a language = Knowing the sounds of language + Knowing how to combine those sounds into word

The Vocal Tract, Oral and Nasal Sound

Place of articulation ① Bilabials : [p],[p’],[p h ][m] -by bringing both lips together ㅂ – 배, ㅃ - 뼈 ㅍ – 폐 ㅁ - 막 (now)

④ Alveolars - By raising the tongue in various ways to the alveolar ridge [t,t’,t h,n] :Tongue tip is raised and touches the ridge, or slightly in front of it. [s] [s’]: Front of tongue is raised, tip is lowered so that air escapes. [l] : Tongue tip is raised while the rest of tongue remains down. And air escapes over its sides (=lateral sound) [r] : The tip of tongue is curled up back the alveolar ridge.(= retroflex sound)

⑤ Palatals : [ ㅈ ],[ ㅉ ],[ ㅊ ] - Constriction occurs by raising the front part of the tongue to the palate ⑥ Velars : [k],[k’],[k h ][ŋ] - By raising the back of tongue to the soft palate(=velum) ⑦ Glottals [h]: From the flow of air through the open glottis, and past the tongue and lips

Aspirated/unaspirated Aspirated sounds are indicated by writing the phonetic symbol with a raised h

In Korean, aspirated sound and unaspirated sound are not allophone. So they are distinctive sound.
