suprasegment

A suprasegment is a human-made phonological category — the concept of a prosodic feature or unit that spans one or more segments rather than constituting a single unit of the sound stream: a property of a stretch of speech (a syllable, a word, a phrase) rather than of any one sound within it. It is the counterpart of segment in the standard dichotomy: segmental description covers the units of the stream (the consonant and vowel inventory), while suprasegmental description covers the properties distributed across those units. Three parameters carve the construct: (1) the property that spans — the prosodic property a language exploits: stress (relative prominence within a word), tone (pitch contrast associated with a syllable or word), length (duration contrast), intonation (pitch movement over a phrase), rhythm (the patterning of prominent and non-prominent units); (2) the span — the sequence of segments across which the feature is distributed, typically a syllable or a word, so a suprasegment is identified by the stretch it covers and the property it carries across that stretch; (3) the system — the language's prosody, which fixes which suprasegmental contrasts are distinctive (stress distinguishes 'REcord' from 'reCORD' in English; tone distinguishes syllables in Mandarin; where a language lacks tonal contrast, pitch is not a distinctive suprasegment). Persistence mechanism: the conventions of phonological description — suprasegmental features are encoded in transcription (stress marks, tone diacritics, length marks, pitch contours), taught as the second half of the segmental/suprasegmental analysis in phonology courses, and operationalized in prosodic phonology, dictionary pronunciation, and speech synthesis.
