| Abstract(in English) | Recently, hands-free speech communication is becoming increasingly necessary for teleconferences, in-car phones, and PC-based IP telephony. Since speech signals acquired by a distant microphone are generally corrupted by ambient noise, noise reduction is indispensable for ensuring speech quality. It is therefore important to investigate the effect of noise reduction on speech quality. We have shown that the PESQ is available to estimate the subjective MOS for noise-reduced speech signals. In this paper, we investigate the applicability of the PESQ to the estimation of the articulation, where the recognition rate is used as its measure. Experimental results confirmed that the human's recognition rate can be accurately estimated by the PESQ. |
