Abstract:Fundamental frequency (Fa) estimation is important in speech processing such as speech coding, synthesis, recognition and so on. A present Fa estimation method performs well under clean condition, however the performance deteriorates significantly in noisy environment. As a result, robust Fa estimation against additive noise is demanded. We have previously proposed Fa estimation methods based on Time-Varying Complex AR (TV-CAR) analysis whose criterion is the weighted correlation of the complex residual obtain… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
