A “phone” is a phonetic unit or segment. The speech sounds we hear and proce ring linguistic communication are all phones. When we hear the following words pronounced:[pit], [tip], [spit], etc., the similar phones we have heard are [p] for one thing, and three different[p]’s, readily making possible the “narrow transcription or diacritics”. Phones may and may not distinguish meaning. A “phoneme” is a phonological unit; it is a unit that is of distinctive value. As an abstract unit, a phoneme is not any particular sound, but rather it is represented or realized by a certain phone in a certain phonetic context. For example, the phoneme[p] is represented differently in [pit], [tip] and [spit].
The phones representing a phoneme are called its “allophones”, i. e., the different (i.e., phones) but do not make one word so phonetically different as to create a new word or a new meaning thereof. So the different[p]’s in the above words are the allophones of the same phoneme[p]. How a phoneme is represented by a phone, or which allophone is to be used, is determined by the phonetic context in which it occurs. But the choice of an allophone is not random. In most cases it is rule-governed; these rules are to be found out by a phonologist.
