     The Queen's English is now sounding less upper-class, a scientific study of the Queen's Christmas

broadcasts had found. Researchers have studied each of her messages to the Commonwealth countries

since 1952 to find out the change in her pronunciation from the noble Upper Received to the Standard

Received.

     Jonathan Harrington, a professor at Germany's University of Munich, wanted to discover whether

accent (口音) changers recorded over the past half century would take place within one person. "As far

as I know, there just is nobody else for whom there is this sort of broadcast records," he said.

     He said the noble way of pronouncing vowels (元音) had gradually lost ground as the noble upper-

class accent over the past years. "Her accent sounds slightly less noble than it did 50 years ago. But these

are very, very small and slow changes that we don't notice from year to year."

     "We may be able to relate it to changes in the social classes," he told The Daily Telegraph, a British

newspaper. "In 1952 she would have been hears saying 'thet men in the bleck het'. Now it would be 'that

man in the black hat'. And 'hame' rather than 'home'. In the 1950s she would have been 'lorst', but by the

1970s 'lost'."

     The Queen's broadcast is a personal message to the Commonwealth countries. Each Christmas, the

10-minute broadcast is put on TV at 3 pm in Britain as many families are recovering from their traditional

turkey lunch. (传统火鸡午餐).

     The results were published (发表) in the Journal of Phonetics.
