Abstract

A novel method to examine the degree to which a two- or three-dimensional space can accurately represent listeners' perception of a large three-formant vowel continuum was examined. As such, the results showed that no two-dimensional representation adequately accounts for listeners' behavior. The key to the analysis was a neural network architecture that will be capable of implementing an optimal, non-parametric, two-dimensional representation of the stimulus space.
