Abstract
A new method for speech analysis is described. It is based on extremes finding in the magnitude spectrum of a speech frame followed by interpolation. The interpolated spectrum envelope can be used for speech synthesis and also for the estimation of the excitation and background noise. In the contribution the proposed method is illustrated using a noisy speech frame and compared with LPC spectrum and spectrum obtained by classical and hidden cepstral smoothing.
