The Seventh ISCA Tutorial and Research Workshop on Speech Synthesis
The present paper addresses the issue of flexibility in expressive unit selection speech synthesis by using different style selection techniques. We select units from a mixed-style unit selection database, using either forced style switching, no control, symbolic target cost, or acoustic target cost as a style selection criterion. We assess the effect of selection technique, feature weight and relative weight of target vs. join costs on a set of objective measures for style specificity and smoothness.
