Models of Generation of Statements of Various Genre Types According to Data of Early Speech Ontogenesis: Imperative Versus Informative Genres

The paper presents computational models of the generation of statements depending on the types of speech genres they belong to. The modeling was carried out on the basis of the primary psychological and linguistic analysis of more than 300 speech products of children of the second year of life in various communicative situations. A system of parameters for assessing natural speech is presented, including intentional complexes—speech motivators, gender categories, speech situations, the speaker's communicative status, and other non-linguistic parameters of statement production. Regression analysis using the method of multinomial logistic regression showed the contribution of a number of social, psychological, communicative factors in the production of genre types which are typical for the specified age. The paper focuses on the results of the regression analysis for the two most frequent types of genres—imperative and informative. It was determined that the differences are associated with the level of contribution in the production of imperatives of needs in a social being, positioning, the need for a material object, the need to prevent damage, to express one's state/thought, the need for cooperation, support, and reflection of the speech strategy; when producing informative statements—the need to change the objective situation.
