A Study On The Monosyllabic Monosyllabic Lip Shape Of Mongolian Language

Based on the pronunciation characteristics of Mongolian standard speech based and use Matlab software to draw a lip model.The dynamics of lips are sequentially recorded by machine and analyzed by scientific methods.On the basis of the study of language,combining traditional dialect research and machine technology and use the way of acoustics experiment.Then we use physiological and acoustic data to analyze and explain lip changes in monosyllabic word pronunciation.Finally,the following conclusions are drawn :(1)By summarizing the lip features of eight short vowels of Mongolian standard sound,the ranking of eight short vowels from large to small is summed up: [a]> [?]> [e]> [i] / [I]/ [o]> [?]> [u].It can be seen from the opening size that the vowel [a] has the largest opening degree.The opening degree of [i] [I] [?] [o] are similar and the [u] is smallest.(2)When an open vowel is sent,with the opening of the outer lip width without increasing significantly.But when a rounded vowel is sent,the width of the outer lip decreases significantly with the decrease of the mouth opening degree.(3)The opening degree of the doubling vowel is in accordance with the order of the monophthong.The largest opening is [ai],the opening of [?i] is larger than that of [ei] and [ui],the smallest opening is [ui].But [ai]?[ei]?[?i] and [ui] due to vowel [i] affects the opening ratio of vowels are significantly smaller the monophthong.The diphthong are not the sum up of two vowels(ai is not equal to a+i).When the diphthong is sent,the two vowels keep a certain characteristic but it is absolutely not the superposition of the two vowels.In this paper,the analysis of the lip position of Mongolian standard sound proves this feature again.(4)When we sent a single word that begins with a vowel,the beginning of the speech on the lip is preceded by its actual pronunciation,and at the end of the speech,its lip shape is later than its actual pronunciation.So when the lip model is built,there should be a change in the lips before and after the beginning of the speech segment.(5)Send to monosyllabic words and at the beginning of the actual bilabial plosive pronunciation and shape change basically synchronous.But at the end of the speech,the lip shape is later than its actual pronunciation.(6)In the CVC structure,the opening degree of the vowel [a] between the two consonants is larger than that of the unit sound [a].This shows that there is a synergetic phenomenon between the vowel and the pre consonant and the postposition consonants.This further demonstrates the conclusion of the predecessors' researchers.To sum up,this study is based on the characteristics of Mongolian standard sound,do a description of the labial features of Mongolian standard sound,the pronunciation characteristics of Mongolian standard sound are obtained and provide more scientific data for the study of Mongolian phonetics.
