정상인의 후두화에 의한 발성 종결 - 개시 지수와 주파수 및 강도 변화 지수와의 상관관계

다국어 초록 (Multilingual Abstract)

This study was designed to investigate the relationship between laryngealization phonatory offset-onset index and frequency and intensity variability index in the connected speech of 13 normal speakers. The acoustic analysis was performed via the Praat 4.3.19. The acoustical characteristics of phonatory offset-onset mechanisms were reflected in spectrographic pattern codes. Codes were applied to laryngealization gestures. Measurement of intervocalic frequency and spectral energy changes was conducted to know the characteristic of laryngealization gestures. L-POI (laryngealization phonatory offset-onset index), P-POI (phonatory offset-onset frequency variability index), and I-POI (phonatory offset-onset intensity variability index: I-POI) were applied to reflect layngealization types, frequency and intensity changes.
  The results of this study were as follows: First, In Korean normal speakers demonstrated 63.1% in pattern 0, 23% in pattern 2, and 14% in pattern 3. There were individuals who preferred patterns in V_V phonetic contexts.
  Second, the Spearman correlation analysis verified the significant relationship between L-POI and P-POI, and I-POI.
  In conclusion, There was no common patterns of laryngelaization among subjects. Laryngelaization was realized with frequency and intensity changes.
