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 1 and L 2 normed LPC (linear predictive coding) models; these results are compared and discussed. The analysis indicates that the L 1-based CD is more robust than more typical L 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
