Analysis and Study on Electroglottograph and Acoustic Test Parametersof Peking Opera Singers

Objective Using Dr.Speech 3.0 software in the multi-media system to conduct synchronizing electroglottograph and acoustic test of vowels like //、/a:/、/i/ pronounced by 137 different roles aged between 20 and 64 and to Compare the results obtained with that of obtained from with healthy voice of common people quality.Methods Dr.Speech 3.0 software in the multi-media system was used to conduct synchronizing electroglottograph and acoustic test of vowels like //、/a:/、/i/ pronounced by 127 different roles aged between 20 and 62 and the results obtained were compared with that of obtained from common people with healthy voice quality.Results The Fo of electroglottography and acoustic test of vowels like //、/a:/、/i/ pronounced by different roles showed remarkable difference.Other electroglottograph parameters like Fo,Jitter,Shimmer,NEE,CQ,CQP and acoustic test parameters such as Fo,Jitter,Shimmer,NEE all have their own parametric values(P0.01,P0.05).So they have statistical significance.The parametric voice values of Peking Opera singers and common people are all within the normal range of DPSS.Conclusion The different roles in Peking Opera have their unique acoustic features and we can use Dr.Speech 3.0 software to do objective test and evaluation of their voice parametric values and provide useful clinical value for vocal training and protection of Peking Opera singers.
