영문 초록

This paper described a speech analysis method by using a LSP(Line Spectrum Pair) parameter which is directly related to spectral enevlope of speech signal. The LSP parameter can be estimated by a distance between the two adjacent formant frequencies which are high resonance frequency in the frequency domain and uses idea that the higher resonance frequency, the narrower distance between the adjacent formant frequencies. In the experiment for the LSP analysis of Korean vowel, 256 data samples are used for the analysis frame and the order of analysis is 10. As the results of experiment, it was obtained that the formant frequency of LSP is the same with the LPC envelope for Korean vowel and the scores of recognition when used the Euclidian Distance method for the PARCOR parameter and the LSP parameter are 91.8% and 93.3%, respectively.
