PROBLEM TO BE SOLVED: To provide a voice synthesizing method suited for obtaining a high- quality synthesized voice in text-to-speech synthesis. SOLUTION: This method produces synthesized voice signals by connecting together the pieces of information that are selected from plural pieces of prestored voice synthesis unit information. In this case, a formant emphasizing filter part 17, in which an LPC that is a voice spectrum parameter for use as a coefficient in a vocal-tract filter part 16, is used as a filter factor 112, is provided, and the formant of the synthesized voice signals is emphasized by the filter 17. |
