The problem of inner speech has been taken up from its origins till today. The very term has been found to be polysemantic. In the history of study of the corresponding phenomenology different psychologists belonging to different trends and generations revealed a number of particular aspects which were assimilated by different scientific approaches. At present it seems obsolete to refer the term to the phenomenon of inner speech train as such. This understanding failed to constitute the mainline in the development of the problem. Nowadays the concepts which try to integrate the inner speech process into a general speech-language mechanism responsible for expression and comprehension of meanings have come into the foreground. It is assumed in them that speech is also an information conveyor, an instrument of communication. Such concepts have much stronger resolving power and better correspond to the systems approach to the study of mind.
