Abstract
A Perceptual Speech Distortion Metric (PSDM) generates perceptual distortion values for voice prompts received from a voice response system by comparing the received voice prompts with reference signals associated with the same states in the voice response system. The perceptual distortion values identify the voice prompts as either correct or incorrect responses to signal generator inputs and also quantify an amount of perceptual distortion in the voice prompts.
