Abstract
The behavior of the CD (cepstral distance) is studied under serveral types of controlled distortion. In addition, CD values are computed from both L/sub 1/ and L/sub 2/ normed LPC (linear predictive coding) models; these results are compared and discussed. The analysis indicates that the L/sub 1/-based CD is more robust than more typical L/sub 2/-based solutions, especially when impulsive-type noise is present. The CD does not appear to be effective for echo-type distortions. However, it provided monotonic behavior for other impairments such as added noise, clipping and low-pass filtering.<>
