Voice modulation design implemented through FPGA and MATLAB

With the rapid development of network technology, there has been an increased demand for real-time signal processing, particularly in the processing speeds of audio and video signals. This paper designs a program for human voice pitch transformation, applied to FPGA hardware, leveraging FPGAs rapid processing filters to achieve real-time voice pitch transformation. In the FPGA program design process, by studying and applying FRM filter design algorithms, the amount of computational data is reduced, thereby enhancing processing speed. Finally, numerical simulation is implemented based on Matlab to verify the feasibility of the program. This provides an approach for the intelligent real-time processing of audio signals.
