A multiple-voice instructing unit ( 17 ) instructs pitch deforming ratio and mixing ratio to a multiple-voice synthesis unit ( 16 ). The multiple voice synthesis unit ( 16 ) generates a standard voice signal by means of waveform superimposition based on voice element data read from a voice element database ( 15 ) and prosodic information from a voice element selecting unit ( 14 ), expands/contracts the time base of the above standard voice signal based on the prosodic information and instruction information from the multiple-voice instructing unit ( 17 ) to change a voice pitch, and mixes the standard voice signal with an expansion/contraction voice signal for outputting via an output terminal ( 18 ). Accordingly, a concurrent vocalization by multiple speakers based on the same text can be implemented without the need of time-division, parallel text analyzing and prosody generating and of adding pitch converting as post-processing. |
