The work purpose - working out of the methods providing as much as possible effective recognition of verbal commands, and their comparison with existing by numerical research. Research method - methods of digital processing and recognition of speech images. Advantages of offered method CFTF-CWT of definition of the fundamental tone concerns: - Absence of in advance set thresholds; - Search of the period of the fundamental tone (without wavelet-transformation) is carried out faster, than in similar methods; - Absence of dependence on noise level as the concrete range of frequencies is investigated. To advantages of the offered methods of creation of a vector of signs of speech signal NQIEL CMC-DFT, CMC-DWT, CMC-CWT the high probability of recognition concerns. Results RSW are introduced in a verbal driving, and also in management fan by installation of the main airing and a hoist engine. VERBAL COMMANDS, EXTRACTION OF THE FUNDAMENTAL TONE, CREATION OF THE FEATURES VECTOR , DIGITAL PROCESSING, RECOGNITION OF SPEECH PATTERN. Conditions of reception of the report: under the contract. 83086, Donetsk, avenue Dzerzhinsky, 7, DAAT.
