PURPOSE:To provide a voice synthesizer which has high quality, requires a smaller amount of memory and accommodates for the generation of voices having various tone quality. CONSTITUTION:The synthesizer is provided with a natural voice element storage means 2 and a feature parameter storage means 3 which extracts parameter vectors that characterize acoustic characteristics such as a vowel normal section against each element of natural voice element sets and stores the position information of the parameter vectors along with the vectors themselves. The feature parameter vectors corresponding to object natural voice elements are made to be targets. A voice synthesizing means 6 synthesizes the voice transition from the targets to desired phonemes, connects them to the natural voice elements so that soft and various tone qualities and intonation are added relative to vowels and high quality voices are provided for consonants. Moreover, the required capacity for the storage of voice elements is made smaller and the connections between voice elements are made smoother. |
