In linguistic research and analysis, phonetic representation refers to the representation of speech sounds in terms of their articulatory, acoustic, or perceptual properties, describing the physical realization of linguistic forms rather than their abstract organization within a language system [1]. It provides a means of encoding the observable characteristics of spoken segments and suprasegmental features through a system of phonetic description [1]. Phonetic representation is distinguished from phonological representation, which concerns abstract sound categories and their structural relationships within a particular language, whereas phonetic representation focuses on the concrete properties of speech production, transmission, and perception [2].
