Sixth European Conference on Speech Communication and Technology
In this paper we propose that prosodic structures in spontancous discourse exhibit both linear and superpositional characterictics, and that these reflect the different scopes of multi-tiered emotional and cognitive processes. The multi-tiered structure encompasses the syllable and word level, interphrase movement, and extended pitch level baseline rise and fall. Analysis of the data suggests that integration of the 3 different prosodic levels within an overall prosodic model provides a critical link for the generation of natural-sounding interactive speech systems.
