Lexicon organization of the Russian child

Abstract

Background: Today, many experts from different areas of a science are interested in close study of children's speech. The items of information on normative speech are especially useful with the purposes of diagnostics of various deviations in speech development. From those items of information, which are accessible at present, researchers try to analyze only acoustic characteristics, early vocalics, their rhythmic structures, etc. We consider that it is necessary to analyze process of formation of the primary dictionary taking into account the articulatory abilities of small children. Methods: The given research managed to be carried out due to video recording of speech behavior of the child that allows objective analysis to be achieved, not only audio material, but also video material of early development of Russian language. Results: We have studied early speech development in six healthy Russian children from 10 months till 2 years old. Video registration and the computer processing of a sound signal of the child has allowed to determine an exact arrangement of children's reports relative to adult ones in dialogue. We have confirmed that it was impossible to receive those data by means of parent's records of the child's early speech that carried subjective character. In result of grading the data, we have received sound structure of the children's statements depending on time of occurrence articulatory abilities. Conclusions: We consider that the data received are very important for all persons, who take part closely in speech development of the child.
