PURPOSE:To allow the synthesis of voices to meet the requirements for naturality and distinctness by selectively using plural different tables and cou pling the voice parameters between elementary pieces. CONSTITUTION:The connection point position of the preceding elementary piece A is indicated by the frame number (a) from the final frame and the connection point position of the succeding elementary piece B is indicated by the frame number (b) from the top frame. The method of connection is indicated by an interpolation function (f). The most adequate connection parameters for respective conditions and characteristics are determined at this time and the respective corresponding tables, for example, (a), (b) are prepd. The voice parameter in the i-th frame (0<=i<=N1) of the connecting part is thereafter calculated. The connecting parameter, such as connecting method and connection point position, are selected by the table number (t) stored in a memory device and are used for each of the characteristics, such as use objects of the synthesized voices, required speaking tone and speaker's characteristics. The distinctness and smoothness of the synthesized voices are obtd. with the balance meeting the condition in this way. |
