This work assesses the contribution of domain-specific prosodic modelling to synthetic speech quality in a name-and-address information service. A prosodic processor analyzes the textual structure of labelled input strings, and inserts markers which spec- ify the intended prosody for the DECtalk text-to-speech synthe- sizer. These markers impose discourse-level prosodic organization, annotate the information structure, and adapt the speaking rate to listeners in real time. In a quantitative comparison of this domain-specific modelling with the default rules in DEC- talk, the domain-specific prosody was found to reduce the tran- scription error rate from 14.6% to 6.4%, reduce the number of repeats requested by listeners from 2.6 to 1.1, and to sound signif- icantly easier to understand and ...
