Approach to creating sets of reference speech commands using ontology

This article describes the method of formation of speech commands reference library using ontology to increase their further recognition. The article presents the formal model of a subject OWL-ontology, used as a base of knowledge in the process of formation and expansion of the library of reference teams in the process of recognition of voice commands. An algorithm for retrieval of the list of synonyms of input speech commands, based on the subject of OWL-ontology is also described. The article describes the research methodology, as well as the results of experiments on the formation of variants of the reference library and selection of a library with the most recognizable commands using OWL-ontology of civil aircraft voice command control. In conclusion, the results of experiments demonstrating the effectiveness of this approach are presented.
