Control systems engineers have recently began using intelligent control instead of classical control to solve many control system problems, because it simulates human thinking and needs less mathematical modeling and deals with non-linear systems much easier. Those facts were the main motivation to use intelligent control to improve the efficiency of speech recognition. In this paper, first speech recognition is defined and explained, then intelligent control, specifically fuzzy logic control, is used to improve the efficiency of speech recognition. Ten numbers, one to ten, were used to test and evaluate the system. Intelligent control proved to be very efficient in situations where classic control fails to recognize one number from another because of the close similarity in their characteristics.
