What are phonologically relevant features?
The phonological relevant features that characterize the phoneme /p/ are, therefore, bilabial, occlusive & fortis. Aspiration, plosive ness, labialization, etc. are phonologically irrelevant features.
Phonologically irrelevant doesn't necessarily mean useless for communication. The aspiration of/p/ helps the listener to distinguish it from /b/ (as in "pride'-'bride','' "pie-buy"). The substitution of one irrelevant feature for another (say, aspirated for non-aspirated) results in a different allophone of one & the same phoneme ([p] aspirated & [p] non-aspirated). Such a substitution does not affect communication.
Every phoneme displays a vast range of variation in connected speech. Among the different types of variation we distinguish idiolectal /'idiəlektl/- èíäèâèäóàëüíûé, diaphonic and allophonic variation.
Idiolectal variation embraces the individual peculiarities of articulating sounds, which are caused by the shape and form of the speaker's speech organs and by his articulatory habits. For instance, a speaker may mumble, or lisp (øåïåëÿâèòü) / say “thish ish” for “this is”/, or stammer (say “a f-f-f-fine d-d-d-day”). Idiolectal variation may cause a lot of difficulties in communication. At the same time it enables people to identify the speech of certain individuals.
