Abstract : Up to 100 time slices and 10 harmonics of visible speech are derived from one single Fourier series. The method assumes a signal-to-noise ratio of better than 1:10. Emphasis has been put on both beat frequency enhancement and carrier suppression. Execution times close to real time were achieved on an IBM 360 Mod 91. Program listings appended to report. (Author)
