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 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 Pāṇini's classification.

Types of phonetics

Phonetics 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.

phonetics and phonology

In contrast to phonetics, phonology is the study of language-specific systems and patterns of sound and gesture. While phonology is grounded in phonetics, it is a distinct area of linguistics, dealing with abstract but psychologically-real sound and gesture units (phonemes) and their variants (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 deals with the physical properties of sounds themselves, not how they are meaningful. There are over a hundred phones recognized as basic by the International Phonetic Association (IPA) and transcribed by simple letters in their International Phonetic Alphabet.

Although "meaningful contrast" between phonemes forms the basis of other discussions of meaning, the subject of semantics does not enter into this level of linguistic analysis.
