: It has been known that noise and reverberation greatly affect the perception of linguistic information, in particular speech intelligibility. However, the effect of noise and reverberation on the perception of non-linguistic information has not been clarified. We investigated how these types of disturbances affect the perception of non-linguistic information (speaker individuality and vocal emotion) of noise-vocoded speech. We conducted speaker-distinction and vocal-emotion-recognition experiments using noise-vocoded speech created from the speech in noisy, reverberation, and noisy reverberant environments as stimuli. We used seven noise conditions (signal-to-noise ratio (SNR) = 1 ; 20 ; 15 ; 10 ; 5 ; 0 ; (cid:3) 5 dB) and six reverberation conditions (reverberation time ( T R ) = 0 : 0 ; 0 : 1 ; 0 : 3 ; 0 : 5 ; 1 : 0 ; 2 : 0 s). In both speaker-distinction and vocal-emotion-recognition experiments, the main effects of noise and reverberation were significant, but the interaction was not significant. From these results, except for extremely poor sound conditions, under daily noise and reverberation conditions (an SNR of more than 10 dB and T R less than 1.0 s), there were no significant effects of noise and reverberation.

: Vietnamese speakers’ mispronunciations of Japanese singleton and geminate stops were identified using the category boundary of the stops pronounced by native Japanese speakers. To clarify the characteristics of the Vietnamese speakers’ mispronunciations, their speech segment durations were analyzed. In comparison with native Japanese speakers’ correct pronunciations, Vietnamese speakers mispronounced a singleton stop with a longer closure and a shorter preceding consonant-vowel segment, whereas they mispronounced a geminate stop with a shorter closure and a longer following consonant-vowel segment. These results were consistent with the findings of Korean, Taiwanese Mandarin, and Thai speakers in previous studies, suggesting that non-native speakers may have a common tendency to have inadequate durations of closure and anteroposterior consonant-vowel segments in mispronunciations of Japanese singleton and geminate stops.
