ABSTRACT:
A frequency bandwidth of a speech signal is divided into a plurality of partial bandwidths. Formant information is extracted on the basis of LPC information developed for the respective partial bandwidths. At least one partial bandwidth may overlap upon the preceding bandwidth. The boundary frequencies of the partial bandwidths can be determined based on the frequency envelope of the speech signal.
