Speech fundamental frequency estimation using the Alternate Comb

Abstract : Reliable estimation of speech fundamental frequency is crucial in the perspective of speech separation. We show that the gross errors on F 0 measurement occur for particular configurations of the periodic structure to be estimated and the other periodic structure used to achieve this estimation. The error families are characterized by a set of two positive integers. The Alternate Comb method uses this knowledge to cancel most of the erroneous solutions. Its efficiency is assessed by an evaluation using a classical pitch database.
