An annotation scheme for concept-to-speech synthesis.

The SOLE concept-to-speech system uses linguistic information provided by an NLG component to improve the intonation of synthetic speech. As the text is generated, the system automatically annotates the text with linguistic information using a set of XML tags which we have developed for this purpose. The annotation is then used by the synthesis component in producing the intonation. We describe the annotation system and discuss our choice of linguistic constructs to annotate.
