An Experimental Phonetic Study of South and North Korean Speech

The aim of this paper is to describe the linguistic differences of two Koreas with a special emphasis on the phonetic aspect of Seoul and Pyongyang speech. The sources of the North Korean speech material used in the study are 1) the Pyongyang radio and TV broadcasts, 2) interviews of north Korean defectors and 3) speech material of north Korean scholars collected by the writer in london, Warsaw, France and China between 1989 and 1994. The most noticeable phonetic differences of Seoul and Pyongyang speech are abstracted as follows: 1) The vowels /이/, /에/ and /애/ are higher and fronter in Pyongyang speech than in Seoul speech. 2) The vowels /우/ and /으/ of Pyongyang speech are somewhat fronter than the corresponding vowels of Seoul speech. 3) The Pyongyang vowels /으/ and if are produced with rounded lips compared to the corresponding Seoul vowels. 4) The Pyongyang vowel /h) is much lower in tongue position and at the same time somewhat fronter than the corresponding Seoul vowel. 5) The consonants /r ,i ,n / are pronounced in Pyongyang as alveolar affricates or something close to them whereas they are pronounced in Seoul as post-alveolar affricates. 6) Unlike in Seoul speech there is a very strong tendency in Pyongyang speech to reduce aspiration feature in consonant seouences such as /ㅂ+ㅎ/, /ㄷ+ㅎ/, /ㄱ+ㅎ/. 7) /ㄴ/ and /ㄹ/(flap) freely occur word-initially in Pyongyang speech whereas they are restricted in Seoul speech. 8) Unlike in Seoul speech the phonemic contrast of long and short vowels are generally not functional in Pyongyang speech. Thus the vowels pronounced long in Seoul speech are usually pronounced short in Pyongyang speech.
