Analysing prosody by means of a double tree structure

Berit Horvei, Georg Ottesen, Sveire Stensby

We have analysed prosody with a view to use the results in a model of prosody suited for a text-to-speech system. To study the prosody an earlier defined double tree data structure of relevant parameters, a data base program, and a query language have been used. The results from the analysis have been used in a parametric model of prosody. We give examples of results from the analysis, and at the end pitch contours generated by the model are compared to pitch contours of text read aloud. It is difficult by listening to distinguish between copy synthesis of the recorded speech and the synthesis of the model.
