Subfields

Phonetics as a research discipline has three main branches:

Phonetics and phonology

In contrast to phonetics, phonology
Phonology

Phonology is the systematic use of sound to encode meaning in any spoken human language, or the field of linguistics studying this use. Just as a language has syntax and vocabulary, it also has a phonology in the sense of a sound system....
 is the study of language-specific systems and patterns of sound and gesture, relating such concerns with other levels and aspects of language. While phonology is grounded in phonetics, it has emerged as a distinct area of linguistics, dealing with abstract systems of sounds and gestural units (e.g, phoneme

es based on shared behavior and phonological processes. Phonetics tends to deal more with the physical properties of sounds and the physiological aspects of speech production and perception. It deals less with how sounds are patterned to encode meaning in language (though overlap in theorizing, research and clinical applications are possible).
