摘要
目的:研究戴用上颌复杂可摘局部义齿对汉语单元音共振峰参数的影响。方法:上颌牙列缺损患者可摘局部义齿戴用前后进行6个单元音的检测并对其前3个共振峰(F)参数进行分析。结果:戴牙后āF1、ēF1下降,ōF1、ēF2、ēF3、īF1、ūF1、ūF2、ǖF2升高。结论:可摘局部义齿修复后,患者的语音功能发生较大变化使用Vsgg语音信号处理系统及Matlab分析程序,能客观地反映语音变化情况,为语音功能的临床评价提供依据。
Objective: To study the effect of maxilla removable partial denture (RPD) on formant of vowels.Method: Result: Testing patients' six vowels before and after restoration of RPD and analyzing F1, F2 and F3. Results: āF1, ōF3, ēF1, ōF1, ēF2, ēF3, īF1, ūF1, ūF2, ǖF2 have significant differences before and after restoration. (α=0.01).Conclusion: Phonetic function changes greatly because of denture restoration. VS99 system together with Matlab program can analyze the acoustic changes objectively and provide evidence for clinical speech evaluation.
