In the article, we consider the idea of developing an intelligent and customizable automated system for maintaining text and voice dialogs with the user in the real time. This system can be used for almost any subject area, for example, to create an automated robot - the operator of the call center or smart chat bots, assistants and so on. The work in details presents module of recognized text phonetic post-processing on the example of the Russian languages.
