Accent

• abstract: Accent is the phonetic prominence given to a particular syllable in a word, or to a particular word within a phrase. When this prominence is produced through greater dynamic force, typically signaled by a combination of amplitude (volume), syllable or vowel length, full articulation of the vowel, and a non-distinctive change in pitch, the result is called stress accent, dynamic accent, or simply stress; when it is produced through pitch alone, it is called pitch accent; and when it is produced through length alone it is called quantitative accent.
