We attempted to enhance the perception of American English III and HI for Japanese speakers by making various modifications to the speech stimuli. Our methods of modification involved spoken, simple acoustic editing, and manipulation through re-synthesis. We discuss the various enhancement methodologies and the supporting perceptual data.
