Korean phonology - Wikipedia

ConsonantsVowelsConsonant AssimilationPhonotacticsVowel HarmonyDialectal Pitch AccentsFurther ReadingKorean has 19 consonant phonemes. For each stop and affricate, there is a three-way contrast between unvoiced segments, which are distinguished as plain, tense, and aspirated. 1. The "plain" segments, sometimes referred to as "lax" or "lenis," are considered to be the more "basic" or unmarked members of the Korean obstruent series. The "plain" segments are also distinguished from the tense and aspirated phonemes by changes in vowel quality, including a relatively lower pitchof the following vowel. 2. The "tense" segments, also referred to as "fortis," "hard," or "glottalized," have eluded precise description and have been the subject of considerable phonetic investigation. In the Korean alphabet as well as all widely used romanization systems for Korean, they are represented as doubled plain segments: ㅃ pp, ㄸ tt, ㅉ jj, ㄲ kk. As it was suggested from the Middle Korean spelling, the tense consonants came from the initial consonant clusters sC-, pC-, psC-.:29, 38, 452 3. The "aspirated...Get price
