1. A system for testing a voice response system, comprising:

  • a signal generator generating inputs for the voice response system;

    a signal recorder receiving voice prompts output by the voice response system in response to the inputs; and

    a perceptual sound quality analyzer outputting perceptual distortion values by comparing the received voice prompts with reference voice prompts, the perceptual distortion values identifying the received voice prompts as either correct or incorrect responses to the signal generator inputs while also identifying different amounts of distortion in the received voice prompts.
