There is provided a synthesized sound generating apparatus and method which can achieve responsive and high-quality speech synthesis based on a real-time convolution operation. Coefficients are generated by using dynamic cutting to extract characteristic information from a first signal. A convolution operation is performed on a second signal using the generated coefficients to generate a synthesized signal. As the convolution operation, an interpolation process is performed on the coefficients to prevent a rapid change in level of the generated synthesized signal upon switching of the coefficients.
