Ciri-ciri akustik tuturan gagap: Kajian fonetik akustik

Abstract

This study aims to formulate the acoustic characteristics of stuttering speech through the acoustic phonetic approach. The parameters used to determine the acoustic characteristics of stuttering speech are the duration of speech and silence, the speech tone contours, and the intensity contours of the speech. The data used in this research is a documentary data taken from the website www.youtube.com. The research data is in the form of stuttering speech with phonetic transcription [bəbəbəp bəbəp bəbəbəp bəlaki]. The data were analyzed using Praat 1.6.26 software. The results show that the analyzed stuttering speech has some acoustic characteristics as follows: (1) it has a different duration per sound segment and tends to increase in the last sound segment which is influenced by the length of the lexical strands and the slow movement of the speakers articulator; (2) it has silences with varying duration between one sound segment and another, which indicates that a stuttering speech is spoken haltingly and often stops suddenly; (3) it has a fairly flat tone contour in the first, second, and third segments, and has a significant increase in tone contour in the last sound segment; and (4) it is spoken louder in the last sound segment compared to the previous sound segment which is characterized by a high increase in sound intensity in the last sound segment.
