Abstract: Objective To find out the influence of different suffix vowel(abbreviation:SV) on the duration of/s/(a voiceless fricative) with acoustic detection method. Methods Two men and two women who were fluent in Mandarin Chinese were recruited in this study. The words included /s/and the suffix vowel /a/,/u/or/i/.The CSL4150 software from Kay Co. was used to analyze the words. Then we compared the durations of/s/when the suffix vowel was /a/,/i/and/u/,respectively. The influence of difference suffix vowel on the duration was exam_ined, and gender effects were also studied on the duration. ResuIts As a voiceless fricative, when the suffix vowel was /a/,the duration for males was 200. 2, and 276. 8 ms for females, respectively. When the suffix vowel was /i/, the duration for males was 218. 2, and 326. 5 ms for females, respectively. When the suffix vowel was /u/,the dura_tion for males was 214. 5, and 302. 9 ms for females, respectively. ConcIusion When the suffix vowel is different, the duration of stop, resistance and in number is different, and also affected by gender.
