Acoustic Comparative Study Of Chinese And Tibetan

Tone which has more comparability is the important speech features of Sino-Tibetan. The paper is based on the research of mandarin tone, to analyze the Tibetan Lhasa words and Xiahe words.First, make a brief explanation in the source of subject, object, meaning, and the domestic and international research status; Secondly, extracting the required parameters from the perspective of modern voice in acoustic methods, for preparing the tone analysis; then according to the acoustic parameters, we summarized the Tibetan tone and two-tone modified tone which based on the Tones types of mandarin and built its tune domain model. Then, make the analysis of the impact on the tone from the glottal stop about Tibetan language in Lhasa. Finally, in the longitudinal comparison of the Tibetan Lhasa words and Xiahe, we make horizontal comparison between mandarin and Tibetan tone, the results are as follows:1) Lhasa has a relatively developed. Tone system which including four kinds of tone and six tone value. It has a clearly difference between high and low two tones. The Xiahe only has the falling tone. Meanwhile, in Lhasa, the tone of the glottal stop will be transferred to a falling tone from the lateral tone.2) The double tone Lhasa words’Modified tone rules:If first syllable is voiceless syllable onsets, besides double plosive tone values are unchanged in QS combination syllables, the others are all changed into level tone, and the second syllable is falling tone; If the first syllable initial is voiced syllable onsets, the rising tone changed into level tone and falling tone, the twists tone into rising tone and falling tone, the second syllable type also changed with the first syllable.3) The two-syllable XiaHe words’tone rules:The first syllable by falling tone changed into level tone, the second syllable unchanged.4) Comparing between Mandarin and Tibetan:Lhasa dialect and mandarin are all grouped into four tone types. In double lexical tone, modified tone in Mandarin is mainly concentrated in the first syllable, the second syllable is basically unchanged, and modified tone in Lhasa dialect are mainly in the first syllable, but the second syllable will also be changed.
