Research On The EGG State Of The Yueyang Plosive

Yueyang dialect's plosive is divided into two categories,one is surd of clear and unaspirated,the other is unstable in form of perform,which cannot be accurately described,Some scholars have recorded it as voiced,some of them are recorded it unaspirated,some are even recorded as voiceless turbidity.There is analyzed by research shows that the plosive's HNR value and the spectral slope of these two sets can be used as an important basis for distinguishing the two sets of initials.In this paper,EGG signal analysis is carried out to the three types of in dialect 's plosive in yueyang.According to the actual situation,it sets up the a coustic type characteristic matrix,and studies the vocalization types of the three types of plosive.Through the 25% reference line that obtains the three types of plosive,base frequency and velocity quotient data,and makes a significant analysis on the average value of Open business of the three types of plosive and the mean of the speed quotient.From the perspective of the open quotient curve,the first step followed by a vowel sound Clear the plenum of plosive and the full turbidity plosive of avera ge value of open business trend is significantly higher than that of the air supply,and the open business trend of the two is basically the same.The characteristics of the gas voice were most obvious in the initial segment of the syllable,and the value of the latter was gradually decreased.In the vowel starting period and stable period of the significant test showed that the pure gas plosive and open commercial value of the turbidity plosive was obviously higher than that of pure gas plosive and inferior plosive and turbidity plosive in average value of open business no obvious difference.From the point of speed,curve,pure gas plosive and turbidity plosive the speed quotient signal trend is basically consistent,in addition to the tone syllables,pure unaspirated plosive syllable speed quotient plosive generally higher than the other two.The three types of plosive traffic movements are stable,showing a slight decline.After a significant test,it was found that there was no significant difference betw een the speed quotient of the three,and the stable segment was gradually convergent.On the fundamental frequency of it,in addition to the tone syllables,flat,on,in the clear unaspirated plosive aspirated plosive in fundamental frequency of the line is the base frequency goes to the same direction.,and basic it is higher than all the turbidity plosive,the turbidity plosive register significantly lower than the other two categories.The total turbidity in the initial segment of the flat and acoustic base frequencies is significantly lower than that of the other two types,and at the end,the three basic frequencies tend to be consistent.At the beginning of the acoustic basic frequency,the three kinds of plosive frequency convergent,the unaspirated and the aspirated of plosive frequency are rising.turbidity plosive frequency are down.After the comprehensive analysis of voice type data,this paper proposed a voice types of distinguishing characteristic matrix,the two types of plosive in Yueyang dialect plosive sound kind of judgment,the conclusion clear unaspirated plosive as normal voice,and clear the plenum plosive and turbidity plosive were belong to gas plosive.
