On the Contribution of Articulatory Features to Speech Synthesis

摘要

There are several features that are used for the unit selection speech synthesis. Among the most used for computing a concatenation cost are energy, F_0 and Mel-frequency cepstrum coefficients (MFCC) that usually give a good description of a speech signal. In our work, we focus on a usage of articulatory features. We want to determine whether they are correlated with MFCC and in that case, if they can replace MFCC or bring a new information into the process of speech synthesis. To obtain the articulatory data, we used electromagnetic articulograph AG501 and then we examined the correlation of two sequences of join costs each described by different features.
