Paper Abstract

Our goal is to provide speech researchers with millimetre accuracy measurements of lip and mouth shape as a function of time. These data are fundamentally important in helping to understand the mechanism of speech production. This paper describes a technique currently under development which is capable of making a full three-dimensional ( 3D) measurement every video frame. Our measurement technique consists of projecting a series of colour-coded stripes of light onto the subject, and measuring a full field of 3D data from the distortion in the pattern visible when viewed from a different angle. A low sampling-rate time-sequence analysis is shown for the mouth of a speaker pronouncing the word power.
