A Study On The Variation Of Entering Tone In The Border Area Of ??Northern Subei Mandarin

The content discussed in this paper is the variation of the sound of the transition zone between the Central Plains Mandarin and the Jianghuai Mandarin.Because of the particularity of the geographical location,the dialect region has obvious transitional characteristics.Some scholars found a transitional zone between the Central Plains Mandarin and the Jianghuai Mandarin during the investigation,and analyzed the transitional features on both sides through the adjustment of the tone and the pronunciation of the finals.This article firstly divides the dialect points investigated into three types according to whether the sound is softened or not,and whether there are three types of dialects,and the changes in the proportion and duration of the dialect points of the three different types of regions.analysis.In addition to analyzing the sound changes in the junction area from the sound relaxation ratio and duration,by plotting the fundamental frequency curve data of the input dialect into the sound words,it can be roughly divided into four types according to the trend of the fundamental frequency curve.These four types represent the four characteristics of the incoming sounds that are far from the boundary between the Central Plains Mandarin and the Jianghuai Mandarin.Whether it is according to whether the sound is softened,whether there is the existence of a throat or the four types of strikes according to the fundamental frequency curve,the sound words in the border area of the dialect are in a state of relaxation,and there is a throat.The end of the Sai-Yin area has a weakening trend.Secondly,the praat speech analysis software is used to further analyze the weakening and falling off of the sound in the area.In the aspect of the larynx,the throat and the tail of the vocal singularity in the border area are both falling off and weakening;In the case of Shuhua,the sound of the transitional area is close to the boundary line.The higher the proportion of the Shuhua is,the closer the length of the sound is to the length of the Shu sound word.The more stable the sound in the boundary line and the transitional area,the lower the proportion of the suffocation;from the change of the phonological rhyme,the phonological rhyme is reduced,and the reduction is first independent with the [-?] into the phonological stop.The sound rhyme re-differentiated into more into the rhyme,but these added rhymes are similar in content to Shu Shengyun,and the closer to the northern part of the Central Plains Mandarin,this feature and the influence of the northern Mandarin is more obvious.Finally,the analysis of the phenomenon of acoustic variation in the region is influenced by the development of the language itself,the influence of the strong Mandarin of the Central Plains Mandarin and the promotion of Putonghua.The evolution trend of the sound is in the direction of Shuhua,and the tail of the throat is gradually Weakened and shedding.
