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 (although this term is often used with a somewhat different meaning; see below). When it is produced through length alone, it is called quantitative accent. English has stress accent.
