Tools for Fundamental Frequency Modelling

Abstract:Numerical modelling of fundamental frequency (F0) is hampered by the lack of suitable tools. This memorandum describes two tools intended to facilitate the exploration of numerical models of F0 and other phrase-level phenomena. One is a modelling program with some unusual characteristics, including input in the form of a description of the prosodic tree, runtime control over parameter settings and rule application, and provision of analysis-by-synthesis facilities that allow analysis-by-synthesis to be carried out using arbitrary mixtures of any utterance types for which the model is defined. The second is an interactive interface to the model that allows it to be manipulated using a programmable time series editor. This allows the user to see immediately the result of changing parameters and enabling and disabling rules, and also allows easy visual comparison of computed values with data.
