This paper addresses the issue of masking of noise in voiced speech. First, we examine the audibility of cyclostationary narrow-band noise added to voiced speech generated by synthetic excitation. Varying the temporal location of noise within a pitch cycle corresponds to varying its phase spectrum. Using this fact, we find that a phase change of the noise in the high frequency region is more perceptible for a low-pitched sound than for a high-pitched sound. We propose a pitch-dependent temporal weighting function and we show experimentally that it is beneficial to the quantization of pitch-cycle waveforms.
