Cue enhancement by stimulus repetition: Natural and synthetic speech comparisons
John E. Hughes Clark, Phillip Dermody, Sallyanne Palethorpe · The Journal of the Acoustical Society of America · 1985
This study investigates perceptual differences between natural and synthesized speech as measured by the effects of stimulus repetition on test item identification accuracy. The results show that identification accuracy is enhanced by repetition for natural speech but not for synthesis, suggesting that there are appreciable differences in their perceptual properties, at least inder the conditions of this experiment.
