It was established that speech sources can be characterized in terms of genetic operating characteristics of the form D kthe square root of N where D is the expected value of spectrum error in dB or a fidelity factor, N is the number of speech spectra categories contained in a pattern library constructed from analysis of the properties of specified speech sources, and k is an experimentally-determined constant that varies in accordance with the entropy of different speech sources. An operating characteristic so established predicts the number of spectrum pattern categories and bit rate required to specify a speech source to any desired level of fidelity. Author
