| Abstract: | In this paper, variations of the short-time FFT spectrum of speech signal clipped symmetrically are analysed. The spectrum correlation coefficients of identical sample at different clipping levels and of different samples at the same clipping level are calculated. The result of experiments provides a basis for development of practical speech recognition systems. |
