【摘要】 汉语方言的差异主要体现在语音上,可以通过计算多个汉字在不同地区的发音差异得到。汉字的音节可分为声母、韵母和声调三部分,声母一般是辅音或零声母,可以从发音部位、发音方法等4个维度描述其特征;韵母由元音或元音加辅音组成,其中的元音特征从舌位高低、舌位前后和唇圆度3个角度刻画;声调用五度标记法表示,这样就建立了用21个特征刻画一个汉字音节的量化模型。对42个代表点之间语音差异的计算结果验证了模型的适用性。更多还原

【Abstract】 The difference among Chinese dialects is mainly reflected in phonetics,which can be quantitively analyzed by calculating the phonetic differences of Chinese characters in different regions.The Chinese syllables commonly consist of three parts: initials,finals and tones.The initials are usually consonants or zero initials,which can be described in four dimensions including pronunciation position and pronunciation method,etc.The finals are vowels or composed of vowels and consonants featured by the height of tongue,the front and back of tongue and the roundness of the lips.Tones are represented by five-level marks.Thus,we formulated a quantitative model to illustrate a Chinese syllable from its 21 features.The calculation results of the phonetic differences in the 42 representative points verify the available of the model.更多还原
