A simplified procedure to determine whether two sounds represent the same or different phonemes. The cases on the extreme left and the extreme right are those in which the sounds are allophones.

In phonology, an allophone (n/; from the Greek: ἄλλος, állos, "other" and φωνή, phōnē, "voice, sound") is one of a set of multiple possible spoken sounds, or phones, or signs used to pronounce a single phoneme in a particular language.[1] For example, [pʰ] (as in pin) and [p] (as in spin, which is less aspirated) are allophones for the phoneme /p/ in English. The specific allophone selected in a given situation is often predictable from the phonetic context, with such allophones being called positional variants, but some allophones occur in free variation. Replacing a sound by another allophone of the same phoneme usually does not change the meaning of a word, but the result may sound non-native or even unintelligible.

Native speakers of a given language perceive one phoneme in the language as a single distinctive sound and are "both unaware of and even shocked by" the allophone variations that are used to pronounce single phonemes.[2][3]

History of concept

The term "allophone" was coined by Benjamin Lee Whorf in the 1940s. In doing so, he placed a cornerstone in consolidating early phoneme theory.[4] The term was popularized by George L. Trager and Bernard Bloch in a 1941 paper on English phonology[5] and went on to become part of standard usage within the American structuralist tradition.[6]
