Dynamic phonology is the natural consequence of the combination of the latest developments in physiological and acoustic phonetics and the traditional structural/functional theories of linguistics. In phonetics, the segmental approach has long since given way to dynamic phonetics, leaving linguists in the position of either ignoring the dynamic evidence and continuing with segmental and semi-segmental phonology or of adopting the dynamic evidence within their overall theories of language structure and function. The author of this book has chosen the latter and here present a model for such a dynamic phonology.
