Abstract
This paper aims to probe into several phenomena typical of spontaneous spoken Czech in informal conversation. It focuses on lexical fillers, formally reduced pronunciation variants and [v]-prothesis (a former regional feature turned stylistic marker in many respects).
These features set informal spoken Czech apart from written language on the one hand, and from formal spoken language, where more attention is given to the form of the message, on the other. In a formal context, all three of these items would be considered as stigmatizing by peers.
The material used to demonstrate these features will consist of publicly accessible corpus data on informal communication in Czech spanning the years 1988-2011, and particularly the ORAL2013 corpus, which provides the most up-to-date material of this sort from all over the territory of the Czech Republic.
