F. Gupta wrote, "Many of the northerners were noticeably hostile to , describing it as 'comical', 'snobbish', 'pompous' or even 'for morons'." On the subject, K. M. Petyt wrote that several respondents "positively said that they did not prefer the long-vowel form or that they really detested it or even that it was incorrect". Mark Newbrook has assigned this phenomenon the name "conscious rejection", and has cited the vowel as "the main instance of conscious rejection of RP" in his research in West Wirral. French words John Wells has argued that, as educated British speakers often attempt to pronounce French names in a French way, there is a case for including (as in bon), and and (as in vingt-et-un), as marginal members of the RP vowel system. He also argues against including other French vowels on the grounds that not many British speakers succeed in distinguishing the vowels in bon and banc, or in rue and roue. However, the Cambridge English Pronouncing Dictionary draws a distinction between (there rendered as ) and the unrounded of banc for a total of four nasal vowels. Alternative notation Not all reference sources use the same system of transcription. Clive Upton devised a separate system for the Shorter Oxford English Dictionary (1993) and this is now used in many other Oxford University Press dictionaries. The linguist Geoff Lindsey has argued that the system of transcription for RP has become outdated and has proposed a new system as a replacement, rather than RP. Lindsey's system is as follows, differences between it and standard transcription are depicted with the usual transcription in brackets. Historical variation Like all accents, RP has changed with time. For example, sound recordings and films from the first half of the 20th century demonstrate that it was usual for speakers of RP to pronounce the sound, as in land, with a vowel close to , so that land would sound similar to a present-day pronunciation of lend. RP is sometimes known as the Queen's English, but recordings show that even Queen Elizabeth II changed her pronunciation over the course of her reign, ceasing to use an -like vowel in words like land. The change in RP may be observed in the home of "BBC English". The BBC accent of the 1950s is distinctly different from today's: a news report from the 1950s is recognisable as such, and a mock-1950s BBC voice is
