음성 환경에 따른 한국어 폐쇄음의 음향적 특성 : 시간적 특성을 중심으로 Some Acoustical Aspects of Korean Stops in Various Utterance Positions : focusing on their temporal characteristics원문보기
The purposes of this study are two-folds: to find out the acoustic features of Korean stops in various utterance positions and their influence on the neighbouring segments. Korean stops($/p,\;p',\;p^{h};\;t,\;t',\;t^{h};\;k,\;k',\;k^{h}/$) are examined from CV, $V_1CV_2,\;V_1NCV_2,\;...
The purposes of this study are two-folds: to find out the acoustic features of Korean stops in various utterance positions and their influence on the neighbouring segments. Korean stops($/p,\;p',\;p^{h};\;t,\;t',\;t^{h};\;k,\;k',\;k^{h}/$) are examined from CV, $V_1CV_2,\;V_1NCV_2,\;V_1LCV_2$ sequences. Three speakers (two male and one female speakers of Seoul dialect) served as subjects for the present study. VOT, closure duration of the target stops and duration of the neighbouring segments were measured from acoustic data. The results can be summarized as follows. First, stops show different temporal aspects depending on their place of articulation as well as their voice types. Velar stops tend to have shorter closure duration and longer VOT due to relatively slower movement of the articulator (i.e. tongue body) and higher supraglottal air pressure during the closure, respectively. Second, temporal aspects of the neighbouring segments appear to be influenced by the voice type of stop. The preceding segment tends to be longer when a stop has shorter duration. On the other hand, the following segment tends to be shorter, when a stop has longer VOT.
