Grammars for the hearers often significantly differ from those for the readers as traditional orthographic notation of wordforms is unable to fully represent the actual expression of the morphological categories and, consequently, the real composition of the paradigms. As a first step for the construction of a grammar for the hearers, one needs a database containing the information on the spoken (phonological) expression of the morphological units. At present the part of the database with the information on Russian nouns is completed. The subjects in the database are Russian noun forms of different declensions and accent paradigms expressing all the types of the stem endings that are able to shape the actual spoken realization of a form.
