Parameter extraction using the winograd fourier transform

J. A. S. Angus, M. T. Whitaker

The Winograd Fourier transform algorithm is designed to minimise the number of multiplications used in calculating the discrete Fourier transform. This makes it suitable for use on a general purpose microprocessor. This paper describes the design of a real time speech parameter extraction system, based on the 68010 microprocessor, and using the Winograd Fourier transform, and compares its performance to systems using the FFT algorithm.
