On autocorrelation equations as applied to speech analysis
John D. Markel, Alfred Gray · IEEE Transactions on Audio and Electroacoustics · 1973
The mathematical theory underlying one of the techniques currently being used in linear prediction of speech is developed from an inner product formulation. This formulation produces a unified framework for studying the properties of autocorrelation equations. In particular, the solution and stability of the auto-correlation equations are studied in detail. Experimental stability results for finite word length analysis of speech are also presented.
