Abstract
This article is about the features of the modern Kazakh language, about synharmony in speech, within words, between words, and sounds. Until now, research has proven that among scientists, there were different opinions about synharmony. Most researchers argue that synharmony is vowel harmony. In our work, we have shown with examples that this also applies to consonant sounds. We have systematically grouped the work of scientists before us, especially researchers who studied the occurrence, pronunciation and auditory characteristics of sounds in the laboratory. We see that the correspondence of both vowels and consonants is of particular importance in determining the direction of personality development and the meaning of monosyllabic words in the modern Kazakh language. When processing the collected material, the emphasis was placed on the function of synharmony in language. The examples were systematized and grouped using comparative and contrastive methods. The participation of the vocal cords was based on the production of signs, and the production of sounds in our language was described by their vibrational waves. It is concluded that if the vocal cord vibrates completely – vowels, if it vibrates more – the tone is dull, if it vibrates partially – dull, and if it does not vibrate at all – solid dull.
