In this paper various auditory masking models recently developed for audio coding are compared and evaluated for telephone bandwidth speech coding applications. Four such models are outlined and their performance evaluated using a Wavelet Packet Transform based subband coder. The models are compared on the basis of the resulting perceptual speech quality and bit rate requirements. Results show that masking models 3 and 4 outlined in this paper provide near transparent quality at the lowest bit rates.
