ABSTRACT

A method for direct solution of the problem on determination of optimal control parameters of a voice information compression system in the process of its development is discussed. It is proposed to use a method of measuring the cepstral distance between the original voice signals and voice signals transformed by the compression system for a rapid speech quality evaluation. A general functional layout of the device for a rapid objective speech quality evaluation by the method of cepstral distance measurement is described.
