Various application fields of linguistics including automatic recognition and speech processing, teaching foreign languages and interpreting colloquial speech, characterization of sociolinguistic speech diversity, linguistic “portrayal” of a certain community (social dialect) and a particular persona (idiolect), linguistic examination (for example, for counter-terrorism efforts), among others, require not only extensive lexical and grammatical resources, but also the description of speech production mechanisms, mainly those, typical of spontaneous speech. Regrettably, the latter are almost always neglected by traditional dictionaries and grammar books, being out of scope of linguistic analysis. The knowledge of such mechanisms is necessary for colloquial studies (colloquialistics) per se, a branch of linguistics which studies everyday spoken language. The authors of this article make an attempt to systematize processes proceeding in modern colloquial language through the reliance on domestic and foreign professional academic literature and research results obtained from the ORD-corpus (everyday Russian spoken language) analysis. The research was fulfilled with the support of RFBR (Russian Foundation for Basic Research) No. 17-29-09175 “Diagnostic features of sociolinguistic variation in Russian everyday spoken language (evidence from a corpus)”.
