PURPOSE: To instantaneously change the speed of a speech in accordance with the operation by a listner by successively outputting voices which are converted in speech speed and requesting voice synthesis data when the amount of accumulation of speech speed-converted voice data is reduced to a prescribed amount. CONSTITUTION: Based on the synthesis request from an output buffer section 1, a voice synthesis section 'k' requests to a segment buffer section 'g' for the data of the starting and ending points of each of voiceless, silent and voiced segments and the starting and ending points of the pitch period of a voiced segment, obtains the necessary data to synthesize a speech speed-converted voice and outputs the converted voice to the section 1 in accordance with the instruction from a conversion magnification setting section 'j' operated by the listner. The section 1 successively outputs speech speed-converted voices, checks whether the amount of the speech speed conversion data being accumulated in the output buffer becomes less than a prescribed amount or not. If it has reached the prescribed amount, a data supply request is issued to the section 'k'. Thus, the speech speed is varied in accordance with the haring capability of the listner and the speed is continuously and instantaneously changed corresponding to the operations by the listner. |
