This paper describes a new model of intonation for English. The paper proposes that intonation can be described using a sequence of rise, fall and connection elements. Pitch accents and boundary rises are described using rise and fall elements, and connection elements are used to describe everything else. Equations can be used to synthesize fundamental frequency (F 0 ) contours from these elements. An automatic labelling system is described which can derive a rise/fall/connection description from any utterance without using prior knowledge or top-down processing. Synthesis and analysis experiments are described using utterances from six speakers of various English accents. An analysis/resynthesis experiment is described which shows that the contours produced by the model are similar to within 3.6 to 7.3 Hz of the originals. An assessment of the automatic labeller shows 72% to 92% agreement between automatic and hand labels. The paper concludes with a comparison between this model and o...

This thesis proposes a phonetic model of English intonation which is a system for linking the phonological and F 0 descriptions of an utterance. It is argued that such a model should take the form of a rigorously defined formal system which does not require any human intuition or expertise to operate. It is also argued that this model should be capable of both analysis (F 0 to phonology) and synthesis (phonology to F 0 ). Existing phonetic models are reviewed and it is shown that none meet the specification for the type of formal model required. A new phonetic model is presented that has three levels of description: the F 0 level, the intermediate level and the phonological level. The intermediate level uses the three basic elements of rise, fall and connection to model F 0 contours. A mathematical equation is specified for each of these elements so that a continuous F 0 contour can be created from a sequence of elements. The phonological system uses H and L to describe high and low pi...

This paper describes a synthesis from analysis scheme for producing natural sounding intonation for speech synthesis. The paper presents a new method of describing F_0 contours in terms of three basic phonetic intonation elements. Details are given of an automatic system for labelling F_0 contours, which could be used for speech recognition purposes. Current work on extracting a phonological description from this phonetic description is discussed.
