Field of the Invention The present invention relates to a speech synthesis apparatus that improves the naturalness by adding phase noise. The present invention relates to an interface circuit for outputting input characters through a data bus, a power spectral envelope for input characters, and a voice algorithm. Adds a phase to the noise applied by the noise generator according to the ROM having a speech synthesis database storing pitch and energy information, a noise generator for generating noise, and an algorithm embedded in the ROM, and reads from the ROM. It converts the power spectrum envelope information and phase noise into high-speed pre, and shifts the pitch information changed from the free by the period of the read from the ROM. Multiply information A central processing unit for outputting the data, a RAM for storing data when the central processing unit executes an algorithm programmed in the ROM, and a digital signal for converting the audio signal synthesized in the central processing unit into an analog signal. It consists of an analog converter, an amplifier for amplifying the analog signal converted by the digital-analog converter, and a speaker for converting the amplified signal through the amplifier into an audio signal and outputting the same.
