Voice “features” in long-term memory
Jody E. Kreiman, George J. Papcun · The Journal of the Acoustical Society of America · 1988
This study examines the perceptual parameters used to recognize an unfamiliar voice (heard only once before) after a one-week delay, as compared to the parameters used to discriminate among the same voices in a short-term memory (paired comparison) task. Ten groups of ten listeners each heard a short sample of a single voice; after seven days, all listeners heard the full ten voice set and had to determine if their target voice was present or not. Confusion data and similarity ratings were gathered and combined to form full matrices that were analyzed using multidimensional scaling. Differences in the perceptual parameters that underlie confusions and perceived similarities in the short- versus the long-term memory tasks will be discussed, as will changes in the relative importance of different parameters with time. The implications of these findings for models of voice perception and speaker recognition will also be addressed.
