Computer Technologies in Spectral Analysis of Uzbek Speech on the Steps of Development of Speech Audiometry for Children

Abstract

The presented article is devoted to the stages of development of speech audiometry in the Uzbek language. The capabilities of Praat computer technology made it possible to conduct a frequency-spectral analysis of Uzbek speech, which formed the basis of speech tables and used in assessing the quality of hearing of school-age children with various hearing impairments. Accordance with the spectral analysis there was revealed: The male voice for the given parameters of sound strength was characterized by the main tone within 80-100 Hz, while the female voice when pronouncing the same words and phrases amounted to 160-175 Hz. Consequently, this fact confirmed that the main tone of the Uzbek language is characterized by a lower basic tone than the Romance and Slavic languages. A qualitative assessment of hearing at the children according to developed speech audiometry in the Uzbek language showed that in cases of sensorineural and conductive, as well as with mixed hearing loss, the influence of the speaker’s gender on speech intelligibility is noted. So, when tested with a male voice, it reaches 100% of the result, but when tested with a female voice in children with III degrees of hearing impairment of 100%, the intelligibility threshold is not observed.
