The Influence of Reverberation on the Perceptual Judgment of Cross-Lingual Speakers’ Timbre
Yali Liu, Mian Wu · 2021
This paper aims at the influence of reverberation on the perceptual judgment of the cross-lingual (English and Mandarin Chinese) speakers’ timbre from the two aspects: perception experiment and acoustic features. The results show that: (1) The reverberation can reduce the identification accuracy of cross-lingual speaker’s timbre, but there is no significant difference in reverberation time. (2) The subjects are more likely to misjudge the same speaker as the different speakers. (3) The perception of the speaker's timbre has significant gender difference, and the misjudgment rate of females is higher than that of males. (4) After adding reverberation, the difference of the average spectrum value between the English and Mandarin Chinese speech has been decreased in the full frequency band. And the difference is reduced to less than 10 dB, in which subjects are more likely to confuse the cross-lingual speakers.
