PURPOSE:To improve the naturalness of a synthesized voice by inserting parameters which indicate the voicing time of each phrase and the strength of the coupling of phrases, and determining whether or not a pause is interposed between adjacent phrases. CONSTITUTION:A character string to be converted into a voice is inputted from a character string input terminal 11. Further, the voicing speed of the whole document when the character string is converted into a voice is inputted from a voicing speed input terminal 12. The input of the voicing speed is specified in speed unit such as a number of mora. Then one of several predetermined stages of voicing speeds is selected. The character string and voicing speed which are inputted are sent to a phrase voicing time calculation part 14, which calculates a voicing time corresponding to the voicing speed of each phrase constituting the document and sends it to a pause insertion position determination part 15. Further, the strength of the coupling of adjacent phrases constituting the document is inputted from a phrase coupling extent input terminal 13 and sent to the determination part. This determination part 15 determines the pause insertion position from the voicing time of each phrase and the strength of the coupling of the phrases. |
