Abstract (in Japanese) (See Japanese page) 
(in English) It could be useful to apply other speaker's speech data to a concatenative speech synthesis system for complementing lack of original speaker's speech database. As a basic study to investigate ability of phoneme replacement, vowels or long vowels of /CVC/ triphone environment in a continuous speech were replaced by other 24 speakers' ones and perceptual naturalness was evaluated. As a result, it tends to show higher naturalness at 1) specified 3 speakers, 2) length of replaced phoneme is short or 3) F0 of replaced phoneme is lower. Furthermore correlation analysis between evaluated value and spectral feature suggests that 1) there is higher correlation at specified 3 frequency bands and 2) spectral peak or dip is related with evaluated value.
