目的:研究正常人不同辅音对元音的影响,为腭裂语音的研究和治疗提供参考。方法:35例在校大学生,男15例,女20例;年龄20～22岁,平均20.43岁。被检音为3组6个音节:/si/-/ji/、/bo/-/po/、/jü/-/qü/。将被检音输入计算机语音工作站CSL4400,测量其元音的音长、基频、前3个共振峰和音强,采用SPSS11.5统计软件对所得数据进行配对t检验。结果:/si/与/ji/的元音音长分别为0.39±0.08和0.31±0.07,第2共振峰分别为2093.55±350.62和2454.33±422.00,有显著性差异(P<0.01);/bo/与/po/的元音音长分别为0.35±0.09和0.53±0.07,音强分别为64.11±4.58和69.94±3.59,有显著性差异(P<0.01);/jü/与/qü/的元音音长分别为0.29±0.07和0.35±0.09。第3共振峰分别为3180.30±301.72和2901.06±259.75,音强分别为68.99±4.59和71.70±5.21,有显著差异(P<0.05)。结论:辅音的送气与否、阻碍的部位和程度均会对后面的元音产生一定影响,但不会改变元音的音质。
Objective: To study the effect of different consonants on vowels in normal people and to provide reference for the study and treatment of cleft palate speech. Methods: 35 college students, 15 males and 20 females; aged 20 to 22 years old, average 20.43 years old. Sent for 3 groups of 6 syllables: / si / - / ji /, / bo / - / po /, / jü / - / qü /. Will be seized into the computer voice workstation CSL4400, measuring the vowel length, fundamental frequency, the first three peaks and sound intensity, the use of SPSS11.5 statistical software on the data paired t test. Results: The vowel lengths of / si / and / ji / were 0.39 ± 0.08 and 0.31 ± 0.07, respectively. The second formant was 2093.55 ± 350.62 and 2454.33 ± 422.00, respectively, with significant difference (P <0.01) The vowel lengths of / / and / po / were 0.35 ± 0.09 and 0.53 ± 0.07, and the sound intensities were 64.11 ± 4.58 and 69.94 ± 3.59, respectively (P <0.01); / jü / and / qü / The vowel lengths were 0.29 ± 0.07 and 0.35 ± 0.09, respectively. The third resonance peak was 3180.30 ± 301.72 and 2901.06 ± 259.75 respectively, and the sound intensities were 68.99 ± 4.59 and 71.70 ± 5.21, respectively (P <0.05). Conclusion: Whether the consonant gas is supplied or not, the position and degree of obstruction will affect the vowel behind, but it will not change the vowel sound quality.
