<p>A phrase editing section (5) retrieves phrase data on a phrase the read of which matches that of a phrase in a fixed message from a phrase database (7) and converts the phrase so as to match the speed specified by utterance speed data. The phrase editing section (5) predicts the prosody of a fixed message and selects an item of the retrieved phrase data most matching each phrase of the fixed message one by one according to the prosody prediction results. However, if the proportion of the phrase corresponding to the selected item of the phrase data does not reach a predetermined value, the selection is cancelled. Concerning the phrase for which selection is not made, waveform data representing the waveform of each unit speech is supplied to a sound processing section (41). The selected phrase data and the supplied waveform data are interconnected thereby to create data representing a synthesized speech. Thus, a speech synthesis device for quickly producing a synthesized speech without any uncomfortable feeling with a simple structure is provided.</p> |
