Abstract
A phoneme information extracting apparatus includes correlation data generators for successively generating correlation data representing the correlation between the acoustic power spectrum data corresponding to input voice and power spectrum data of various reference phonemes, selection circuits for successively transferring these correlation data when they detect that three or more successive correlation data have values greater than a predetermined value, maximum data hold circuits for holding the maximum correlation data among the correlation data transferred from the respective selection circuits, and a phoneme determination circuit for determining the optimum phoneme by detecting one of the data hold circuits that is holding the maximum correlation data among the correlation data held in the data hold circuits.
