title: The effect of noise envelope modulation on quality judgments of noisy speech.
abstract: This study aims to evaluate how speech quality is affected by noise which varies in modulation from 0% (the lowest correlation with the speech envelope) to 100% (the highest correlation with the speech envelope). Using a scaled paired-comparison forced-choice procedure, ten normal-hearing listeners rated overall preference, noisiness, and distortion of speech stimuli with different noise modulation percentages at 0, 10, and 20 dB signal-to-noise ratios. As noise modulation percentage increased, ratings for overall preference increased, ratings for distortion increased, and ratings for noisiness decreased. The noise modulation effects on quality ratings were significant, even at the same signal-to-noise ratio.
