The Tone Study Of Dege In Tibetain

Tone is an important feature of the Sino-Tibetan language family, which have an impact on the pitch by varying meanings. Tibetan language, because the relationshp between the evolution of speech, resulting in a tonal language. Based on the Tibetan dialects Dege tone acoustic analysis to identify Dege dialect word reconcile the twin tone tone and modulation rule.First, the subject of sources, research subject, significance and research status are briefly described; secondly, the status quo Tibetan tone reviewed, including the Central Tibetan language, Lhasa dialect, Amdo Tibetan has already produced sound Madoi tone bit value words; then from the perspective of modern phonetics, with acoustic instruments to extract words Dege tone parameters to prepare for the next acoustic analysis; and then based on the parameters were extracted acoustic analysis, Dege words summed up the word reconcile the tone type and tone laws twin tone and build the range model; Finally, the differentiation conditions Dege Tibetan words tones. Summarized as follows:1. Barry words tone tone system is still at the stage of change, do not have stability. Experiments have two words come to DegeA transfer class, four tone value, the level of two clearly different tune.2. Dege then double-word tone modulation law is more complex, there are many forms of modulation:Before voiced initials, QS all goes flat Tune; before QC, ZC, ZS, QS, etc. all become demotion. Between two syllables, one of the more obvious transposition occurs, both transfer are almost no changes.3. The models range from Dege words, the girls range range significantly higher than boys, but boys field width is greater than Girls.4. Barrydifferentiation conditions, then pitched tone in line with the development of "pure low cloud," the law, from Dege words sound, rhyme The impact on the tone of the mother can be found, is consonant voicing affect the tone of the initial conditions, then Dege differentiation; secondly, to simplify complex consonant tones also occur if Dege differentiation; final consonants shedding affecting Dege The third factor, then tone.
