A more important difference is the greater clearness with which Americans pronounce unaccented syllables. They do not say secret’ry or necess’ry. An American speaker is easily recognized because he accents the third syllable of necessary. Conversely the suppression of syllables in Britain has been complained by EFL learners who are not used to the position of the chief stress and weak forms. The British commonly say centen’ary and labor’ atory, and adver’ tisement is never advertise’ ment. There is also the matter of pitch and tempo. Americans speak more slowly and with less variety of tone. For some English speakers, American speech sounds bit more monotonous, uttered with less variety in the intonation than that of British, but easier to understand. (Pyles 1982: 227-228)
