ResumoThe voice communication between humans and machines is the idea people have been thinking about a long time. For high level of the voice communication with the control system it is important to ensure good quality of the speech signal processing with additive noise in real environments. This paper describes a proposed method for optimal adjustment parameters of the adaptive filter with an LMS algorithm in the practical application of suppression of additive noise in a speech signal for voice communication with the control system. By the proposed method, the optimal values of parameters of an adaptive filter are calculated which guarantees the stability and convergence of the LMS algorithm. The experimental section of the paper describes a way of verification of the proposed method on the adaptive filter with the LMS algorithm and on the LMS adaptive noise canceller by simulations in the MATLAB software and implementation on the digital signal processor TMS320C6713.
