Abstract
Prosody templates, constructed during system design, store intonation (F0) and duration information based on syllabic stress patterns for the target word. The prosody templates are constructed so that words exhibiting the same stress pattern will be assigned the same prosody template. The prosody template information is preferably stored in a normalized form to reduce noise level in the statistical measures. The synthesizer uses a word dictionary that specifies the stress patterns associated with each stored word. These stress patterns are used to access the prosody template database. F0 and duration information is then extracted from the selected template, de-normalized and applied to the phonemic information to produce a natural human-sounding prosody in the synthesized output.
