The Acoustic Analysis Of The Fricatives Of Torgod Sub-dialect

By using Praat and Mini Speech Lab, we are researching the fricatives of Torgod sub-dialect fricative, Mainly based on the relevant parameters in the database of speech. This research describes the phonetic features of fricatives with the help of Acoustic pattern.There are introduction, chapter first, chapter second, chapter third, conclusion and appendix in this thesis. The introduction provides the general distribution of oirad dialect, previous research situation, intention and the meaning of selection, the choice to the research approach and four sub-dialect.First chapter analyzes Torgod sub-dialect fricatives in various environments by using SPG, and also makes dynamic and static research description on the resonance hump of fricatives on the word level. Chapter second makes dynamic and static research description on Fricative duration and intensity on the word level. With space diagram and pattern, Chapter third demonstrates Center of gravity and dispersion of Torgod sub-dialect, showing the dispersion characteristics of fricatives.summing up the content and points which are appeared in the above, there can be the conclusion that the breach sound of/s//f//x/can approximately reach to two different item trends./s//f/can be as one item./x/as another. For/s//f/, thier formants are relatively higher, duration is longer, intensity is stronger. In terms of the energy concentrated, they are area relatively higher and their dispersions are relatively lower. are for/x/, It’s formant is lower and duration is shortor, intensity is weaker. In the terms of the energy concentated area, It is relatively lower and its dispersion is relatively higher. In the end. there are also conclusion that voiced. fricative/z/has two anamorphosises like [z][z].
