Accents and dialects provoke strong prejudices and reactions. In a 40 Minutes film that examines why this should be, broadcaster Janet Street-Porter, Radio 4 announcer Susan Rae and actor Peter Bowles are among those who have suffered because of the way they speak. Meet the Queen's English Society, which keeps a candle burning for the purity of the spoken word, and the Devon Dialect Society, which has very different ideas about how vowels should sound. Eavesdrop on an elocution class, hear from Scottish schoolchildren whose accents might affect their job prospects, and go behind the scenes at the BBC Pronunciation Unit and the northern auditions for the Speaking Clock.
