The Comparative Research On Phonological Structure Distribution And Combination Ability Of Chinese And Tibetan

Phoneme is an important part of language system, but also the basic elements of language phonetic system. The research on concrete phonemes in the Tibetan and Chinese can reveal the structure characteristics of Chinese and Tibetan phonetic system, and lay the foundation of the research on sino-tibetan system in the future at the same time. This paper based on the modern standard Chinese commonly used2500words and modern Tibetan5190words, and take two language’s consonant phoneme system as the basic research object and take the closed space and large balance corpus as the basic scope. Based on the theory of linguistics, phonology and statistics, to do statistics and comparison research on phoneme distribution patterns, the structure of the phoneme, the combination relationship between different phoneme and the ability of combination the different phonemes in Chinese and Tibetan character database. Namely to statistic using frequency of initials phoneme, finals phoneme and tones phoneme within different language use scope to research phoneme distribution patterns and characteristics. From the combination weight of different initial type and different final type to research the combination relations and combination ability of different phonemes in Chinese and Tibetan phonetic system. According to comparative analysis the characteristics of phonological structure in Chinese and Tibetan phonetic system,to explore the rule of the evolution of sino-tibetan language phonological system.According to compare the characteristics of phoneme system structure and phoneme combination ability of Chinese and Tibetan.It can be found that the distribution of Chinese and Tibetan phoneme in the phonological system structure is similarity. On the total frequency distribution, the distribution of Chinese and Tibetan phoneme in the each other enclosed space is balancer than they distribute in large balance corpus.It can be seen that, in a closed space system, the distribution of phoneme in Chinese and Tibetan is relatively stable. Specific performance for,(1) On pronunciation part,the initials of Chinese and Tibetan in different pronunciation part,the more front of the initial pronunciation part is, the more stronger the combination ability of initial is, then the weaker conversely. On pronunciation method characterized by plosive, affricate initials which has strong air flow, also has absolute quantity advantage and high frequency in initial phonemes,then combination ability of them are strong.(2) In finals, the structure type of Chinese and Tibetan is similar to each other. Consonant end finals are showing outstanding frequency distribution and activity combination both in Chinese and Tibetan phonetic system.(3) In tones, several tones in Chinese and Tibetan present a state of imbalance frequency distribution. In Chinese and Tibetan phoneme system, the combination ability of all kinds of phoneme have positive correlation to its own quantity and its own frequency value.The research of this paper reflects the structure of all kinds of phoneme and distribution pattern, the combination relationship and combination ability between phonemes in Chinese and Tibetan phonetic system and Tibetan phonetic system. Provided the certain reference data for the research of Chinese and Tibetan phonetic system and the study of the development evolution of phonemes in Chinese and Tibetan phoneme. As well as laid the foundation for the development and evolution of the sino-tibetan language research and also provides a certain reference value.
