Abstract: PURPOSE: A synthesizer for synthesizing a single voice into multiple voices using a pitch changing method is provided to synthesize a single voice into multiple voices by changing a pitch. CONSTITUTION: A pitch is detected by applying the amplitude characteristic and period characteristic of a voiceprint. The detected pitch is extended by 140%, 120% and is compressed by 80%, 60% by using a PSOLA(Pitch Synchronous Overwrap and Add) pitch changing method. The extended and compressed pitches are synthesized, leaving some delay, so that multiple voice synthesized sound is generated. A voice signal waveform in an analog type is amplified in an amplifier. The amplified voice signal waveform passes through a low band pass filter to remove aliasing effect, and passes through an analog-to-digital converter to be quantized and coded, so that the voice signal waveform is converted into a digital signal in a PCM(Pulse Code Modulation) type. The digital signal is processed by software or firmware in a CPU or a digital signal processor.
