<p>A voice synthesizer for editing and synthesizing sound element segments extracted from an analog voice waveform, which converts an analog voice signal into a digital signal, relatively shifts data in the vicinity of the rear end of the preceding sound element segment and data in the vicinity of the end of the following sound element segment by arithmetic control means to calculate the degree of similarity and clocks out the data of the following sound element segment from memory means so that the following sound element segment is connected in the smoothest manner to the preceding sound element segment. Accordingly, the abrupt variation in the waveform produced at the connector between the preceding sound element segment and the following sound element segment, i.e., high frequency noise based on the discontinuity of the waveform, the deterioration of S/N ratio of the synthesized sound and the deterioration of the articulation can be almost eliminated, and synthesized sound having no discontinuous waveform and no variation in the pitch frequency at the connector can be obtained.</p> |
