Abstract
The method of performing a time-domain approximation of the speech wave in terms of a linear combination of Gaussian wave packets is evaluated as a signal processing tool. This set of functions is used because of their ease of extraction from the original signal and their versatility. The parameters defining the set of functions are determined from the times and magnitudes of extrema in the band-limited signal. Because the wave packets used to represent the signal are analytically transformable to the frequency domain, various characteristics, such as the Fourier spectrum and the autocorrelation function, may be evaluated directly from the parameters describing the wave packets. The economics and accuracy of this technique are discussed.
