| Summary: | 碩士 === 大葉大學 === 汽車電子產業研發碩士專班 === 97 === In this paper the grey prediction of grey theory is applied in studying the speech analysis. For the purpose of involving in the creature innovation, the Levinson-Durbin method is adopted for extracting the poles to build the speech model. There are two most parts contribute as: (1) By means of the MATLAB package extracts the poles data which is established by the process of the speech files using microphone and constructed in a data-base storage at the same time. (2)In order to qualify the quantity of the speech data, the AR (Auto regression) model filter is considered in the AWGN environments. The simulation results will show that not only the method of suppressing speech noise is proposed, but a speech model is also established for increasing the speed of speech processing. It is an expectation for providing with another choice to promote the performance of speech recognize.
