An allophone is a phonetic variant of a phoneme in a particular language. In phonology, an allophone (from the Greek: állos, "other") is one of a set of multiple possible spoken sounds (or phones) used to pronounce a single phoneme. For example, [pʰ] (as in pin) and [p] (as in spin) are allophones for the phoneme /p/ in the English language.
• [p] and [pH] are allophones of the phoneme /p/.
• [t] and [tH] are allophones of the phoneme /t/.
