Abstract (in Japanese) (See Japanese page) 
(in English) We investigated a single-ended speech intelligibility estimation method that does not require clean speech reference signal, using the features defined in the ITU-T standard P.563. Four hundred noise samples were added to speech, and about 70% of these samples were used to extract the feature sets to train an estimation model using the support vector regression (SVR). The trained models were used to estimate the intelligibility for speech degraded with the remaining 30% of unknown noise samples. The proposed method showed a root mean square Error (RMSE) value of about 0.16 and correlation with subjective intelligibility of about 0.84 for speech distorted with unknown noise with either of the feature set. These results were comparable or higher than the double-ended estimation which require the clean reference signal.
