食管发音与发音管发音的声学参数分析

Acoustic parameter analysis of oesophageal voice and tracheo esophageal prosthetic voice

目的:探索多维语音分析系统(Multi-DimensionalVoiceProgram,MDVP)的声学参数分析对食管发音和发音管发音检测的适用性,总结出适合这类语音检测的声学参数。方法:选择食管发音患者20例,Blom-Singer发音管患者18例。首先对这类发音进行主观评价,通过5分制对其评分。声学参数分析采用美国KayElemetrics公司的MDVP。结果:①主观评价结果和声学参数中的多项参数间存在显著的相关性(P<0.05或P<0.01)②多项声学参数之间存在显著的相关性(P<0.05或P<0.01)。③主成分分析将声学参数相关矩阵合成6个因子,其中可以对其命名的因子为5个因子。主成分分析的结果与MDVP声学参数的分类基本吻合以及声学参数与主观评价间存在相关性,都证明了MDVP能够很好地用于对于食管发音和发音管发音的分析。结论:MDVP能够很好地用于对食管发音和发音管发音的检测。基频扰动、噪声、和语音的持续能力这3项特性是影响普通听者对这类语音质量评价的主要因素。

AIM:To explore the application of the acoustic parameter analysis system of Multi Dimensional Voice Program(MDVP)in oesophageal voice and the tracheo esophageal prosthetic voice, and to summarize the acoustic parameters by analyzing the voice quality. METHODS:Twenty subjects were laryngectomized esophageal speaker, and 18 were laryngectomized, tracheo esophageal speaker.Perceptual evaluation was applied and 5 five point scales were used to grade. MDVP of Kay Elemetrics was used to analyze the acoustic parameters. RESULTS:①Significant Pearson correlation(P< 0.05 or P< 0.01)was found between the subjective evaluation and many of the acoustic parameters.②Significant Pearson correlation was found among many of the acoustic parameters(P< 0.05 or P< 0.01).③Principal component analysis(PCA) decomposed the correlation matrix of acoustic parameters into 6 factors.Five of them could be named.The consistency of the results of PCA and the classification of acoustic parameters, along with the correlation between the acoustic parameters and subjective evaluation, attested that MDVP could be applied in the analysis of oesophageal voice and the tracheo esophageal prosthetic voice. CONCLUSION:MDVP analyses system can be applied in the inspection of oesophageal voice and the tracheo esophageal prosthetic voice. Fundamental frequency perturbation, noise, sustained uninterrupted ability of voice are the main influences that affect ordinary people's evaluation of the quality of oesophageal voice and the tracheo esophageal prosthetic voice.
