This paper addresses the issue of choosing the optimal number of informative parameters in the solution of voice control. This paper consists of three parts. The first part provides an overview of fundamentals of acoustics speech and speech production. Are the basic concepts of acoustics, speech and their physical meaning. The second part provides an overview of the informative parameters characterizing speech signals. It is shown that the acoustic characteristics of voices can be divided into five categories: prosodic, dynamic, phonational, spectral and energy. In the third section briefly discusses the classification of speech recognition and voice control system parameters. Are the most effective informative parameters of speech signals used in the system voice control.
