ABSTRACT
Objective:To observe the acoustic characteristics of glottal stops produced by patients with cleft palate.Methods:Twenty boys with cleft palate who were judged to be glottal-stop-producers and 20 normal peers were included. In their own way, all the children were asked to produce following sounds: /iu/ /pai/ /t′u/, /s/ /k′/ /p′u/ /t′u/, /tA/ /ku/ and /i/ /k′u/ /ti/ /suan/. Then the speech spectroanalysis and the comparison were performed by one investigator.Results:The acoustic characteristics of glottal stops changed a lot when they substitute or accompany with different oral stops, which included the emergence of spikes, changes of voice onset time, the formant transitions and spetroanalysis of spikes. Conclusion:The acoustic changes of glottal stops are complicated. Every single aspects of acoustic analysis should be considered in the identification of the acoustic characteristics.
