A semi-blind negentropy maximization algorithm for enhancing a specific speech

Abstract: Extraction of a specific speech signal from convolutive mixtures of multiple speeches is a challenge since different speeches may share similar characteristics. Based on our semiblind negentropy maximization algorithm for separating multiple speech signals, we further present an algorithm for extracting a desired speech by constructing a corresponding reference signal. Specifically, two kinds of reference signals are explored, which include a clear speech from the specific speaker and a rough estimation of bli… Show more
