Abstract
A multiple-voice instructing unit () instructs pitch deforming ratio and mixing ratio to a multiple-voice synthesis unit (). The multiple voice synthesis unit () generates a standard voice signal by means of waveform superimposition based on voice element data read from a voice element database () and prosodic information from a voice element selecting unit (), 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 () to change a voice pitch, and mixes the standard voice signal with an expansion/contraction voice signal for outputting via an output terminal (). 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.
