From Text to Prosody W
نویسنده
چکیده
A new method for predicting prosodic parameters, i.e. phone durations and F0 targets, from preprocessed text is presented. The prosody model comprises a set of CARTs, which are learned from a large database of labeled speech. This database need not be annotated with Tone and Break Indices (ToBI labels). Instead, a simpler symbolic prosodic description is created by a bootstrapping method. The method had been applied to one Spanish and two German speakers. For the German voices, two listening tests showed a significant preference for the new method over a more traditional approach of prosody prediction, based on hand-crafted rules.

متن کاملCorrelating Text with Prosody
The prediction of prosody from text information has long been recognised as a requirement for natural sounding speech synthesis. While an examination of the relationship between text information and prosody typically focuses on the role of accent, duration and phrasing both from a statistical and rulebased perspective, this paper investigates the correlation between the similarities calculated ...
