Glottal Closure Instant Estimation using an Appropriateness Measure of the Source and Continuity Constraints

Abstract

An algorithm for GCI (glottal closure instants) estimation is presented in this paper. It relies on a source filter model of speech production using a LF model for the source component. From this source filter decomposition, a ratio which measures the goodness of fit of the LF source model is introduced in the GCI estimation procedure together with fundamental frequency constraints. Then a Viterbi algorithm is applied to extract the most likely GCI sequence. Experiments performed on a real speech database show the relevance of the proposed method
