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
