The paper describes an interface between generator and synthesizer of the German language concept-to-speech system VieCtoS. It discusses phenomena in German intonation that depend on the interaction between grammatical dependencies (projection of information structure into syntax) and prosodic context (performancerelated modifications to intonation patterns). Phonological processing in our system comprises segmental as well as suprasegmental dimensions such as syllabification, modification of word stress positions, and a symbolic encoding of intonation. . | From Information structure to Intonation A Phonological Interface for Concept-to-Speech Hannes Pirker Georg Niklfeld Johannes Matiasek and Harald Trost hannes georgn John harald @ Austrian Research Institute for Artificial Intelligence OFAI Schotteng. 3 A-1010 Vienna Austria Department of Medical Cybernetics and Artificial Intelligence University of Vienna Freyung 6 A-1010 Vienna Austria Abstract The paper describes an interface between generator and synthesizer of the German language concept-to-speech system VieCtoS. It discusses phenomena in German intonation that depend on the interaction between grammatical dependencies projection of information structure into syntax and prosodic context performance-related modifications to intonation patterns . Phonological processing in our system comprises segmental as well as suprasegmental dimensions such as syllabification modification of word stress positions and a symbolic encoding of intonation. Phonological phenomena often touch upon more than one of these dimensions so that mutual accessibility of the data structures on each dimension had to be ensured. We present a linear representation of the multidimensional phonological data based on a straightforward linearization convention which suffices to bring this conceptually multilinear data set under the scope of the well-known processing techniques for two-level morphology. 1 Introduction The task of interfacing between a tactical generator and a speech synthesizer is two-fold A grammatical description enriched with semantic and pragmatic features has to be translated into a qualitative phonological description which then has to be mapped onto the set of quantitative parameter values needed as input to the synthesizer. The requirements imposed by a concept-to-speech system differ from those on both text generation and text-to-speech systems.
