Narrow transcription


Phonetic transcription (also known as phonetic script or phonetic notation) is the visual representation of speech sounds (or phones). The most common type of phonetic transcription uses a phonetic alphabet, such as the International Phonetic Alphabet.

The pronunciation of words in many languages, as distinct from their written form (orthography), has undergone significant change over time. Pronunciation can also vary greatly among dialects of a language. Standard orthography in some languages, particularly French, English, and Irish, is often irregular, and makes it difficult to predict pronunciation from spelling. For example, the words bough and through do not rhyme in English, even though their spellings might suggest they do. In French, the sequence "-ent" is pronounced /ɑ̃/ in accent, but is silent in "posent".

Other languages, such as Spanish and Italian have a more consistent—though still imperfect—relationship between orthography and pronunciation (phonemic orthography).

Therefore, phonetic transcription can provide a function that orthography cannot. It displays a one-to-one relationship between symbols and sounds, unlike traditional writing systems. Phonetic transcription allows us to step outside orthography and examine differences in pronunciation between dialects within a given language, as well as to identify changes in pronunciation that may take place over time.

Phonetic transcription may aim to transcribe the phonology of a language, or it may be used to go further and specify the precise phonetic realisation. In all systems of transcription there is a distinction between broad transcription and narrow transcription. Broad transcription indicates only the most noticeable phonetic features of an utterance, whereas narrow transcription encodes more information about the phonetic variations of the specific allophones in the utterance. The difference between broad and narrow is a continuum. One particular form of a broad transcription is a phonemic transcription, which disregards all allophonic difference, and, as the name implies, is not really a phonetic transcription at all (but at times coincides with it), but a representation of phonemic structure.
