6446-447 ABSTRACT The invention is a technique for reducing the amount of calculation necessary for the pulse search in multi-pulse coding of a speech signal. This involves adding crosscorrelations between an impulse response of a synthetic filter without pitch prediction and an impulse response of a synthetic filter with pitch pre- diction, thereby determining autocorrelations of the impulse response of the synthetic filter with pitch prediction. Another step is adding crosscorrelations between the impulse response of the synthetic filter without pitch prediction and an input speech signal to determine crosscorrelations between the impulse response of the synthetic filter with pitch prediction and the input speech signal.
