Synthesising contextually appropriate intonation in limited domains

A dialogue system with contextually appropriate spoken output intonation

We demonstrate the production of spoken output with contextually appropriate intonation in the information-state based dialogue system GoDiS. We exploit the context representation in the information state to determine the information structure of system utterances, which we use to control the intonation of synthesized spoken output.

Producing Contextually Appropriate Intonation In An Information-State Based Dialogue System

Producing Contextually Appropriate Intonation is an Information-State Based Dialogue System

Our goal is to improve the contextual appropriateness of spoken output in a dialogue system. We explore the use of the information state to determine the information structure of system utterances. We concentrate on the realization of information structure by intonation. We present the results of evaluating the contextual appropriateness of varied system output produced with a text-to-speech sy...

Generating Contextually Appropriate Intonation

One source of unnaturalness in the output of text-to-speech systems stems from the involvement of algorithmically generated default intonation contours, applied under minimal control from syntax and semantics. It is a tribute both to the resilience of human language understanding and to the ingenuity of the inventors of these algorithms that the results are as intelligible as they are. However,...

An Information Structural Approach to Spoken Language Generation

This paper presents an architecture for the generation of spoken monologues with contextually appropriate intonation. A twotiered information structure representation is used in the high-level content planning and sentence planning stages of generation to produce e cient, coherent speech that makes certain discourse relationships, such as explicit contrasts, appropriately salient. The system is...
