The Acoustic Research Of Mongolian Tone Voice

Tone folk song has a long history and a unique style. It shows the Mongolian nationality is the most beautiful and the most typical style of culture. Currently, the most of the research is about the style and rhythm characteristics, these alone for the traditional theoretical research of folk songs to protect and inherit a mass culture is not enough. So in this thesis, with the folk long songs of Inner Mongolia’s Alxa League as object of the research, and extract the related parameters of speech signals and an EGG to study the Mongolian long-tune with the digital design techniques.Through the analysis of the speech and voice signal, this thesis mainly draw the following conclusion:(1)When singing, the energy of voice is not only bigger than speaking, the span of the minimum and maximum span is bigger than speech sounds. Girl singing in the energy distribution is scattered.(2) The folk long songs have the singing formant.(3)The minimum and maximum fundamental frequency of singing is bigger than reading, which illustrates the range of singing is wider than the range of reading.(4) The open quotient of the Falsettos part always remain around50%and the opening and closing phase of vocal cords are equal. The fundamental frequency and speed quotient of the falsetto and tremolo shows a negative correlation relationship.From the perspective of acoustics and physiology, this study analyzed the characteristics of the Mongolian long-tune and laid the foundation for further study on the perception of Mongolian long-tune. It also provides some basic data for voice research and some preliminary ideas with regards to acoustic standards.
