Phonetics

Phonetics (from the Greek φωνή ("phonê") "sound" or "voice") is the study of the physical sounds of human speech. It is concerned with the physical properties of speech sounds (phones), and the processes of their physiological production, auditory reception, and neurophysiological perception.

Phonetics was studied as early as 2,500 years ago in ancient India, with Unicode|Pāṇini's account of the place and manner of articulation of consonants in his 5th century BC treatise on Sanskrit. The major Indic alphabets today order their consonants according to Unicode|Pāṇini's classification.

Types of phonetics

Phonetics as a research discipline has three main branches:
*articulatory phonetics is concerned with the articulation of speech: The position, shape, and movement of "articulators" or speech organs, such as the lips, tongue, and vocal folds.
*acoustic phonetics is concerned with acoustics of speech: The properties of the sound waves, such as their frequency and harmonics.
*auditory phonetics is concerned with speech perception: How sound is received by the inner ear and perceived by the brain.

It also includes a fourth branch:
*forensic phonetics is the use of phonetics (the science of speech) for forensic (legal) purposes.

Phonetics and phonology

In contrast to phonetics, phonology 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, features, mora, etc.) and their variants (e.g., allophones), the distinctive properties (features) which form the basis of meaningful contrast between these units, and their classification into natural classes 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).
