VOICE SYNTHESIS DATA GENERATING DEVICE, VOICE SYNTHESIZING DEVICE, VOICE SYNTHESIS DATA GENERATING PROGRAM, AND VOICE SYNTHESIZING PROGRAM

摘要

PPROBLEM TO BE SOLVED: To easily generate voice synthesis data for generating a natural synthesized voice. PSOLUTION: An input voice waveform 1 is analyzed by a segmentation part 3, a pitch detection part 4, and a sound volume detection part 5 respectively, and segment information showing continuance lengths of a phoneme symbol and a phoneme, pitch information showing variation in pitch, and sound volume information showing variation in sound volume are outputted. Further, a timbre data detection part 7 of a timbre information extraction part 6 applies a timbre analysis of the same kind with an object voice synthesis part 12 to the input voice waveform 1 and a timbre difference extraction part 10 outputs the difference value between the analysis result and dictionary data of a corresponding phoneme as timbre data. A voice synthesis data generation part 11 generates voice synthesis data from the segment information, pitch information, sound volume information, and timbre data. The voice synthesis part 12 to which the voice synthesis data are inputted varies frame data read out of a dictionary by the pitch information, sound volume information, and timbre data, synthesizes a voice based upon the varied frame data, and outputs the synthesized voice.
