ABSTRACT OF THE DISCLOSURE A voice synthesizing system for synthesizing a voice from voice parameters containing acoustic parameters which express vocal tract transmission characteristics and voice source parameters which express the intensity and type of a sound source and from pitch information as described. The synthesizer includes a voice parameter input for supplying the voice parameters for predetermined frames and a non-voice parameter generator for generating parameters to synthesize a non-voice sound. An internal status detector receives connecting data containing the number of non-voice frames, the number of voice parameter frames and the number of parameter interpolation frames and counts each of the numbers to detect the internal status of the synthesizer. A parameter selector selects either an output from the voice parameter input or an output from the non-voice parameter generator in response to an output from the internal status detector. A parameter interpolator interpolates an output from the parameter selector in response to the output of the internal status detector. A pitch interpolator performs the interpolation of a pitch on the basis of pitch information having a pitch value at an arbitrary point and its interpolation period. A voice is synthesized in response to the output of the parameter interpolator and pitch interpolator.
