The phoneme is an abstract termThe phoneme is an abstract term (a speech (a speech sound as it exists in the mind of the speaker) and sound as it exists in the mind of the speaker) and it is specific to a particular language. it is specific to a particular language.

The sounds corresponding to the letter The sounds corresponding to the letter ´́tt´́ in the English words 'tea' and 'trip' in the English words 'tea' and 'trip' are not in fact quite the same. The are not in fact quite the same. The position of the tongue is slightly position of the tongue is slightly different, which causes a difference in different, which causes a difference in sound detectable by an instrument such sound detectable by an instrument such as a speech spectrograph. Thus the [t] as a speech spectrograph. Thus the [t] in 'tea' and the [t] in 'trip' are in 'tea' and the [t] in 'trip' are allophones of the phoneme /t/.allophones of the phoneme /t/.
