Multi-closure-interval Linear Prediction Analysis Based on Phase Equalization

摘要：

This paper presents a multi-closure-interval linear prediction (MCLP) analysis based on phase equalization in order to remove the effect of subglottal resonance in speech signals for estimating a vocal-tract spectrum. The validity of this method is evaluated by using a vocal-tract simulator that models vocaltract losses and the subglottal system. Results show that the proposed method improves the estimation accuracy of a vocaltract spectrum compared with the conventional MCLP method.
