Abstract
The aim of the research is finding acoustic parameters suitable to determine the severity of the disorder in children with developmental dysphasia. On the basis of subjective listening tests conducted by experts and laymen, patients were divided into three groups according to the severity of developmental dysphasia (mild, moderate and severe form of disorder).
After analyzes of the same voice and speech utterances healthy children and children with developmental dysphasia include such parameters suitable for the categorization of speakers in each group. Objective evaluation of patients speaking with developmental dysphasia should facilitate diagnosis and evaluate the current level of speech development, articulation and classification of the severity of the disorder.
