Abstract(in English) | In order to estimate degradation of naturalness in concatenative speech synthesis due to mismatch of phonetic environments between unit selection and its use, perceptual experiments were conducted using speech stimuli synthesized by concatenating V and CV extracted from separate utterances. The results for substitution of the succeeding environment of a vowel showed that (1) the naturalness was low when a vowel segment was used before [y, w]; (2) environments of extraction and usage asymmetrically affected the naturalness. On the other hand, the results for substitution of the preceding environment of a consonant showed that the naturalhess was (1) high for vowel [i], while the naturalness was low for [N, a]; (2) affected more by the kind of consonant than by the preceding environment; (3) especially high when consonant was voiceless plosives, affricates, and fricatives. |
