One source of unnaturalness in the output of text-to-speech systems stems from the in- volvement of algorithmically generated de- fault intonation contours, applied under minimal control from syntax and semantics. It is a tribute both to the resilience of hu- man language understanding and to the in- genuity of the inventors of these algorithms that the results are as intelligible as they are. However, the result is very frequently unnatural, and may on occasion mislead the hearer. This paper extends earlier work on the relation between syntax and intonation in language understanding in Combinatory Categorial Grammar (CCG). A generator with a simple and domain-independent dis- course model can be used to direct synthe- sis of intonation contours for responses to data-base queries, to conve...
