Acoustic Research Of Consonants Of Amdo Tibetan In Tianzhu

In anduo Tibetan day wish words pronunciation characteristics as the research object, extract parameters, acoustic parameters with precise analysis of the acoustic characteristics of amdo Tibetan day wish words, and make analysis to language visible figure. Using Syntrillum released more tracks editing tools for Adobe Audition and speech science at the university of Amsterdam in the Netherlands institute development Praat used in speech analysis and synthesis of a series of software of anduo Tibetan day wish consonant parameters are detailed in this paper. Through the study, briefly summarizes the amdo Tibetan day wish words voice change. Using the amdo Tibetan day wish words voice parameters for library ", chosen from the database including media, fricative tenuis, turbidity, qing fricative and lateral, and extract the statistical analysis of acoustic parameters of the selected word sums up its sound intensity, formant and consonant length distribution, using the method of experimental phonetics and statistics and theoretical knowledge of anduo Tibetan day wish consonants acoustic analysis and research, describes the acoustic characteristics, some conclusions are drawn, for natural language processing in Tibetan speech recognition, speech synthesis and Tibetan language teaching research provides the reference data.In this paper, the main conclusions are the following:(1) Unaspirated plosive [p], [t], and [k] the length of the average around 20 ms, b asic and glottal stop [(?)] have a relatively short length according to the time parameter, the size of the relationship is in turn:[t]<[(?)]< [p]< [k], according to extract the amp litude parameter analysis, the relationship between the size, in turn, is:[t]<[(?)]<[p]< [k].(2) The plenum plosive length difference than unaspirated plosive, larger size rel ations, in turn, [th]<[kh]< [ph], by analyzing amplitude, retroflex plosive smaller amp litude of the [th], and it is smaller than other gas delivery plosive strength.(3) Four nasal [m], [n], [?], [?] between the first and the second formant resonant difference size order for [?]<[n]< [m]< [?], and the second formant and the first for mant difference position can be determined before and after, so you can launch [?] the tongue of the top, followed by [n], and [?]tongue is relative.(4) Days wish words unaspirated affricate pronounce with both men and women [ts] friction period of time average minimum, followed by [te], and then to [ts]. Order from small to large, respectively [ts]< [t(?)]< [ts], plenum affricate order for[tsh]< [t(?)h] < [tsh], and unaspirated affricate than plenum affricate standard deviation is small, s ay I wish tomorrow, unaspirated affricate pronunciation than the plenum affricate stab ility.
