Phonetics[1] is the study of sounds produced by the human voice - speech sounds in particular. It is concerned with the actual properties of speech sounds as well as those of non-speech sounds, and their production, audition and perception, as opposed to phonology, which is the study of abstract units (such as phonemes and distinctive features) which underlie both speech and writing. Phonetics deals with the sounds themselves, as articulated, acoustic, and audited phenomena, rather than with the contexts in which they are used in languages. While writing systems and alphabets often attempt to represent the sounds of speech, phoneticians are more concerned with the sounds themselves than the symbols used to represent them.
Phonetics has three main branches:
- articulatory phonetics, concerned with the positions and movements of the lips, tongue, vocal tract and folds and other speech organs in producing speech;
- acoustic phonetics, concerned with the properties of the sound waves and how they are received by the inner ear;
- auditory phonetics, concerned with speech perception, principally how the brain forms perceptual representations of the input it receives.
Phonetics is generally considered to be a field of modern linguistics, though sometimes 'Linguistics and Phonetics' is found in the literature, indicating that phonetics in itself is not always directly concerned with the sounds of language. Indeed, phoneticians may make reference to sounds that are physically possible to produce, but unattested in any languages. The front low vowel [ɶ], for instance, seems to be absent from the phonology and phonetics of the world's languages, though inevitably this claim has not gone unchallenged.
There are over a hundred different phones recognized as distinctive by the International Phonetic Association (IPA) and transcribed in the International Phonetic Alphabet.
Phonetics was studied as early as 2500 years ago in ancient India, with Pāṇini's account of the place and manner of articulation of consonants in his 5th century BCE treatise on Sanskrit. The major Indic alphabets today, except Tamil script, order their consonants according to Pāṇini's classification.
Phonetics often involves modern technology to analyse speech. This spectrogram as used in acoustic phonetics shows the frequencies of vibrations involved in the production of six British English vowels by an adult male native speaker: from left to right, the vowels as in bee, sue, herd, or, bar and buy. The bands of energy (formants) are distinctive for each vowel; for example, the lower the bottom formant ('F1'), the higher the vowel is articulated in the mouth.
