In order to broaden the utility of objective methods for perceptual evaluation of ultrawide-band (sampled at 48 kHz) speech, two extensions to the W-PESQ standard are proposed. In one approach the psychoacoustic model of W-PESQ is expanded to cover higher frequencies by means of data extrapolation. In the alternative method the psychoacoustic model is replaced with that of PEAQ. A performance analysis of both methods reveals that their predictions strongly correlate with measured mean opinion scores (MOS), bearing a cross-correlation coefficient around 97%. Tests used speech signals corrupted with white and broad-band environmental noises.
