Richard Ogden: Email rao1@york.ac.uk Institution Experimental Phonetics Laboratory, Dept of Language and Linguistic Science, University of York, Heslington, YORK YO1 5DD, U.K. Status (ex-)Research Associate Associations British Association of Academic Phoneticians, IPA, IoA Research I have been working with John Local and, earlier, John Coleman on YorkTalk (http://www.york.ac.uk/~lang4/Yorktalk.html) a computational implementation of Firthian Prosodic Analysis (http://www.york.ac.uk/~rao1/firthian.html). The model used by YorkTalk is monostratal, monotonic and declarative. It uses unification and compositional parametric and temporal phonetic interpretation. I have worked largely on temporal interpretation within YorkTalk. I have also worked on a Prosodic Analysis of the Latinate class of English words. Prosodic analysis allows for single unchanging roots and suffixes to be stated while also accounting for precise phonetics and constraining the morphological combination of roots and suffixes. By stating acceptable Latinate structures it is possible to decide whether novel input is Latinate or not. This work is the subject of a patent application. More recently, I have been working on the Firthian understanding of phonetic exponency (http://www.york.ac.uk/~rao1/exponency_principles.html), and trying to formulate it into a set of principles. Phonetic exponency is implicit in the Firthian literature, but not elaborated into a theory. My work is based on Firthian literature, and also our experience in speech synthesis.
