Predicting Prosodic Phrasing

Pepi Stavropoulou

In principle, the longest phonological phrase possible would coincide with the maximum time elapsed, before people would need to take a breath. However, in practice, Phonological Phrases are never that long and speakers impose a much finer and richer partition on the utterances they render. In the project presented an attempt is made to explore the reasons underlying the speakers' choice on prosodization and identify regularities and constraints primarily diverse in nature, aiming at a more informed choice in PP prediction for Text to Speech Synthesis.The work departs from the comparison between two different proposals on the relation between syntactic and prosodic structure, namely:
a) the set of constraints developed by H. Truckenbrodt (1999) within an Optimality Theory framework and building on an edge-based approach to the conditions governing the syntactic and phonological component interface,
b) M.Steedman's (2000) theory according to which the prosody of the utterance is determined in terms of Information Structure alone, the latter reflected on the more flexible syntactic surface structure of Combinatory Categorical Grammar.
All research is based on a set of approximately 600 sentences from the BU Radio News Corpus.
