摘要
目的探讨鼻流量、时长及元音稳定段第二共振峰等声学参数在区分前后鼻韵母中的作用。方法分析30名被试鼻韵母的声学参数，分别比较前鼻韵母、后鼻韵的鼻流量、时长、元音稳定段第二共振峰的差异。结果前后鼻韵母鼻流量、时长、元音稳定段第二共振峰具有极其显著的差异。结论鼻流量、时长、元音稳定段第二共振峰可作为区分前后鼻韵母的有效参数，在临床中可用来评价和监控前后鼻韵母发音异常的临床治疗效果。
Objective To investigate the effects of acoustic parameters（nasal flow, duration and the second resonance peak of vowel segment） in differentiating front and back nasal finals. Methods This study analyzed the acoustic parameters of 30 subjects and compared the differences between front and back nasal finals in nasal flow, duration and the second resonance peak of vowel segment. Results There were significant differences between the front and back nasal finals in nasal flow, duration and the second resonance peak of vowel segment. Conclusion Nasal flow, duration and the second resonance peak of vowel segment can be effective parameters in distinguishing between front and back nasal finals and can be used to assess and monitor the clinical treatment outcomes.
