Abstract: Objective To study acoustic characteristics of vowel in normal people aged from 6 to18 for research and treatment in cleft palate speech. Methods 60 normal people who aged from 6 to18 was divided into three groups (Group A: 6~12 years; Group B: 13~15 years; Group C: 16~18 years),with 10 males and 10 females in each group. The test material /a:/,/i:/,/u:/, was collected and analyzed by the first three formant frequency (F1、F2、F3) and fundamental frequency (F0) with VS-99 computer speech laboratory. Results (1) There was no significant difference in F1, F2, F3 and F0 among the three groups (P > 0.05). (2)Significant difference was demonstrated in F0 between male and female in both group B and group C (P < 0.05). (3) There was no significant difference in all the measurements in females among the three groups (P > 0.05), but significant difference was demonstrated in F0 in males among the three groups (P < 0.05). Conclusion We should establish different acoustic F0 standards due to different sex and age when evaluating cleft palate speech.

摘要:

目的 探讨6~18岁正常人群的元音声学特点,为腭裂患者语音治疗提供参考。方法 选取2010年11月至2011年9月在南昌大学附属口腔医院正畸科初诊的6~18岁正常人60名(男、女各30名),按年龄段分为3组(A组:6~12岁;B组:13~15岁; C组:16~18岁),每组男、女各10名。采用VS-99语音工作站对各组研究对象发单元音/a:/、/i:/、/u:/时进行录音,并对其前3个共振峰(F1、F2、F3)及基频(F0)测量值进行比较分析。结果 (1)3组间比较,发单元音/a:/、/i:/、/u:/时,F1、F2、F3及F0差异无统计学意义(P>0.05)。(2)3组内不同性别间比较,A组发各元音时的F1、F2、F3及F0差异无统计学意义(P>0.05);B、C组除F0差异有统计学意义(P<0.05)外,F1、F2、F3差异均无统计学意义(P>0. 05)。(4)3组间相同性别比较,女性发各元音时的F1、F2、F3及F0差异均无统计学意义(P>0.05),男性F1、F2、F3差异无统计学意义(P>0.05),而F0差异有统计学意义(P<0.05)。结论 发单元音/a:/、/i:/、/u:/时,随着年龄的增长,女性的F1、F2、F3及F0无明显变化;男性的F1、F2、F3无明显变化,但青春期前后,F0 变化明显。我们对腭裂语音进行评估时,可考虑建立共同的F1、F2、F3参考值体系,但应根据年龄、性别而使用不同的F0参考值。
