Fujisaki superimpositional models

A number of amendments have been proposed to the Fujisaki model aimed at giving it more flexibility for modelling languages other than Japanese for which it was originally designed. For instance, Van Santen et al [465], [467], [411] have proposed a model which allows more than one type of phrase contour, and allows the modelling of micro-prosodic effects as well as detailed alignment of the contour to the phones. The principle of superimposition is attractive in itself as it seems intuitive to model different parts or functions of the FO contour separately and then combine these to produce the final contour for the utterance. This has lead to other t5q)es of superimpositional models, for instance the superposition of functional contours model of Bailly and Holm [31], discussed in detail in Section 9.6.4. 

Some models have a superimpositional nature (Dutch, Fujisaki) where pitch accents are seen as being relatively short term which riding on top of a phrases which are seen as being relatively long. By contrast, in linear models (AM/Tilt) contours are composed of linear sequences of in-...
