Abstract
A listener's ability to recognize and identify similar sounds is improved by testing the listener's ability to recognize and identify exaggerated sounds that are formed from pairs of similar sounds. The exaggerated sounds differ from one another in spectral/temporal energy distribution more that the similar sounds differ from one another and in generally the same way in which the similar sounds differ. The exaggerated sounds are formed as follows: the similar sounds are spectrally transformed into a coordinate space and a linear function is projected between a pair of points. To exaggerate the sounds, points are extrapolated outward from the pair of points along a linear function. The listener is challenged to repeatedly identify each of the exaggerated sounds. When the listener has demonstrated proficiency, the degree to which the exaggerated sounds differ from the similar sounds is reduced and the listener is again challenged.
