The Phonatory Aerodynamics Of Baoan Language Phonemes

As a precious minority language in our country,Baoan language is derived from the Mongolian.In the language of ownership security language Baoan language belongs to the Altai language family of Mongolia.In the process of language contact,Baoan language under the influence of Chinese,Tibetan and other ethnic language,which occurred many changes.This paper mainly studies the Phoneme of Baoan language in the process of pronunciation in terms of the change of airflow and air pressure from the experimental point of view for the evolution of the Phoneme.This study provides support for the establishment of the language protection,speech correction and the establishment of the physiological parameters of Altai.Airflow and air pressure play an important role in the process of pronunciation.This paper studies the phoneme of vowel and consonant in Baoan language from the phonatory aerodynamics.By extracting phonation time,expiratory airflow duration,peak expiratory airflow,expiratory volume,glottal resistance,aerodynamic efficiency and other physiological parameters,the article draws the following conclusions.In the vowel:by extracting speech aerodynamic parameters,the article pointed out that the physiological characteristics of vowel and the corresponding relationship between the aerodynamic parameters and pronunciation position.On the one hand,it can detail the description of vowel phoneme.On the other hand,it is necessary to verify the induction of vowel phonemes in the brief introduction of Baoan language.Through the comparison of vowels in Chinese,Mongolian and Baoan language,from the angle of language contact explain and verify the voice,and the article points out that the future in the process of language contact short vowel will gradually disappear from the vowel system or transfer to the other.In the consonant:from the perspective of speech aerodynamics,the physiological characteristics of consonant sounds are explained.The physiological parameters of pattern are established to plosive and affricate.At the same time,in this paper the classification of consonants is carried out from the angle of air pressure and airflow,which are taken as the distinguishing features of the consonant.Through the synchronic comparison of the phonetic system of the Baoan language,Tibetan language and the Chinese language,this paper explains the causes of voiced consonants and verifies it from the perspective of the phonetic aerodynamics.From the point of view of language contact,we can see that the semi voiced consonants in Baoan language will evolve into a new phoneme,and the nature of the semi turbid will gradually disappear,evolving into a voiceless consonant.In order devoicing,unaspirated voiced affricates earlier than unaspirated voiced stops.
