This article describes the methods of developing a system of speech recognition, speech translation into a foreign language, and speech synthesis. Objective: to examine the relevance of developing such systems, to consider the business processes in the field of international communication, to identify system requirements, to describe the methods of developing such systems and analysis of existing solutions.
This article discusses the following design methods: analysis of models of existing solutions and building a model of the future solutions on this basis, building a data flow diagram (DFD-model), building an entity-relationship diagram (ERD-model).
In describing of the problem of developing of the system have been solved several non-trivial problems, such as reading the speech, analysis, translation into a foreign language, simulation of the speaker’s voice.
For the implementation of speech analysis methods are applied, which are used in the voice cloning: Spectral analysis of the speech signal based on the fast Fourier transform, mathematical dynamic programming unit (DP-method), the algorithm of a marking of pitches of the speech signal.
Discussed in this article a system of speech processing allows to simplify the communication between different cultures.


Problem of international communication, system of speech processing, automatic speech processing, speech recognition, speech analysis, speech translation, speech synthesis, voice cloning, speech cloning.
