Zirneeva G. Information technology of processing and the analysis of characteristics of the speech information

Object of research - processes of processing of the information about speech signals at the analysis and recognition. The purpose of researches - increase of speed and reliability of recognition of speech signals on the basis of the constructed information technology of the analysis, processing and approach of spectra of speech signals. Research methods: the theory of processing of speech signals; the theory of the spectral analysis; the recognition theory; the optimization theory; probability theory and the mathematical statistics; the theory of technology of designing of information systems and the theory of object-oriented programming. Scientific novelty - new methods of recognition of speech signals on the basis of a principle of a Pontryagin's maximum and on the basis of local extrema for the first time are offered; for the first time the method of comparison of realizations of a signal of variable length which in difference from the existing establishes conformity of inputs of a neural network and elements of the shown realization is offered; The method of construction of analytical approach spectral - time representation of a speech signal is improved; the hierarchical model is improved multicriterion. Practical value consists in creation of information technology on the basis of the offered models and methods; to working out of program "SpeechSAnalysis environment which realizes the offered information technology. Introduction degree - within the limits of branch. Sphere (branch) of application - various control systems and automation.
