THE PHONOLOGICAL SYSTEM OF MODERN MANDARIN CHINESE AND THE PHENOMENON OF PHONOVARIABILITY: A THEORETICAL AND FUNCTIONAL ANALYSIS

This study analyzes the phonological system of modern Mandarin Chinese and its major characteristics. The research examines the syllabic structure of Mandarin Chinese, including initials, finals, and tones, as well as segmental units and the functional aspects of the tonal system based on scientific sources. In addition, tone sandhi, the phonetic features of the neutral tone, the phenomenon of erhua (rhotic suffixation), and assimilation processes are discussed in detail. Special attention is devoted to the issue of phonovariability, including alternative pronunciation forms, reduction, elision, speech-rate-dependent changes, and sociolinguistic and regional variability factors. As a result, the study demonstrates that the phonological system of Mandarin Chinese, while possessing a rigid structural foundation, simultaneously represents a dynamic system characterized by a high degree of variability in actual speech.
