Abstract (in Japanese) (See Japanese page) 
(in English) We have suggested that the auditory system can extract the size information and separate it from vocal-tract shape information. For example, humans can extract the message from the voices of adult and child without being confused by the size information, and they can extract the size information without being confused by the message. There were several size perception experiments about acoustically scaled vowels, syllables, musical instruments and animal voice. In this paper, we extended the size perception experiments to naturally spoken and whispered speech words to demonstrate that size perception is robust to the variation in the utterance (voiced and whispered). This results show that the size discrimination JND of both of voiced and whispered speech is almost the same and the recognition performance remains good beyond the normal range.
