PROSODIC AND ORTHOEPIC NORMS IN KAZAKH SPEECH SYNTHESIS

The article addresses the issues of prosodic and orthophonic norms in the speech synthesis of the Kazakh language. Currently, there is a growing need to develop and improve speech synthesis for the Kazakh language. This need is linked to the rapid development of modern technologies and artificial intelligence, which has stimulated relevant research. The article emphasizes the importance of improving speech synthesis, as well as the need for accurate reading by announcers in accordance with orthophonic norms and the precise conveyance of prosodic features. For the study, a 62-page text from the 11th-grade “Kazakh Literature” textbook was used. The text examines phonetic phenomena such as segmentation into syntagms, harmony of vowels and consonants, agreement between roots and affixes, changes between rhythmic groups, assimilation, dissimilation, reduction, variation, and elision, all in accordance with orthophonic norms. In addition, to ensure natural speech synthesis in accordance with orthoepic and prosodic norms, an algorithm was developed to describe sound changes within words, at word boundaries, and between rhythmic groups, and the text was annotated with prosodic markup. The educational material was subjected to prosodic analysis, during which eight intonemes characteristic of the Kazakh language and described by academician Z.M. Bazarbaeva were used.
