I think when somebody refers to perfect english is a very subjective thing, for example for a person born in London, nobody in the U.S. has a perfect english, as well as for a person born in NY, that will be perfect english and the british are not that perfect to them

Generally ''perfect English'' is regarded to be RP (received pronunciation) in England. http://en.wikipedia.org/wiki/Received_Pronunciation

I think the closest that you'll find to "perfect english" is in the pacific northwest. (washington, oregon, idaho, and nevada) the people there realy dont speak with an accent. if a person follows all the rules of english without changing anything then that can be considered "perfect english". thnk of people in new york. they dont pronounce their "R's" like in park they say it like "Pok" that is not following the ruls... R's are not supposed to be silent. in texas they say "cindy" and "sandy" exactly the same way, they both sound like "sandy". they do the same thing with "texas" and "taxes", both sound like taxes. plus they add way to many sylibals to each word.

1) You speak perfect English when you don't need subtitles on TV: "Perfect English" http://www.youtube.com/watch?v=qK3ppRnasQA 2) "Standard English (often shortened to S.E. within linguistic circles) is a term generally applied to a form of the English language that is thought to be normative for educated users. There are no set rules or vocabulary for any putative "Standard English" because, unlike languages such as French, Italian, Spanish, Dutch or Danish, English does not have a governing body (see Académie française, Accademia della Crusca, Asociación de Academias de la Lengua Española, Nederlandse Taalunie, Dansk Sprognævn) to establish usage." "The English language, although originating in England, is now spoken as a first language in many countries of the world, each of which may have developed one or more "national standards" of pronunciation, grammar, or vocabulary. Furthermore, English has become the most widely used second language, [1] and is therefore subject to alteration by non-native speakers. Numerous "non-native dialects" are developing their own standards—those, for example, of English language publications published in countries where English is generally learned as a foreign language. According to Peter Trudgill, "Standard English is that set of grammatical and lexical forms which is typically used in speech and writing by educated native speakers. It includes the use of colloquial and slang vocabulary, as well as swear words and taboo expressions." This definition is also often used by American linguists. Most linguists recognise that the notion of a standard English that covers all native speakers, educated or not, would be very difficult to articulate. This definition refers to grammar and vocabulary and not to pronunciation. Trudgill claims that Standard English is only spoken by a very small part of the population of the British Isles (about 12-15%). Further, Standard English speakers often speak in regional and class accents. One might expect that Standard English speakers would use a particular pronunciation, for example Received Pronunciation (RP) in the UK, or General American in the US. In fact, less than a third of the speakers of UK Standard English have an RP accent, with the rest of the speakers using their own regional accents, which shows that standard dialect and regional accent do not exclude each other. In the US, regional variations in pronunciation are somewhat less than the UK; many Americans speak with a General American pronunciation. However regional dialect variations are intensifying according to the research of William Labov. Trudgill concludes in this matter, that "Standard English is a dialect that differs from the others in that it has greater prestige, does not have an associated accent and does not form part of a dialect continuum". Hence, Standard English is purely a social dialect. As the result of historical migrations of English-speaking populations and colonisation, the predominant use of English as the international language of trade and commerce and its widespread use outside exclusively English-speaking countries, English has risen to the status of a global lingua franca. The effects of local native languages on the creation of creoles or pidgins have contributed the evolution of the many local and regional varieties of English."

In perfect English, the local replies that he can't actually speak English." http://en.wikipedia.org/wiki/Big_Train - "When he pulled off the road, a giant flying object looking much like a diesel locomotive pulled past him and landed in front of his car. A hatch opened in the rear and a woman wearing a sort of face mask with goggles came out, pulled off the face mask, and greeted him warmly by name. The woman spoke perfect English, and while pretty, looked like an ordinary human. However, she claimed to be from the planet Mercury." http://en.wikipedia.org/wiki/Dan_Martin - "Erich Kordt (10 December 1903 - 11 November 1969), German diplomat, was involved in the German Resistance to the regime of Adolf Hitler. Kordt was a convinced Anglophile, and spoke perfect English after gaining a Rhodes Scholarship to Oxford." http://en.wikipedia.org/wiki/Erich_Kordt - "Both Mr. and Mrs. Rogaum are German immigrants and speak with heavy German accents and at times using German words and grammar. In contrast to her parents, Theresa, who has lived in America her entire life, speaks with no German accent, and speaks with almost perfect English." http://en.wikipedia.org/wiki/Old_Rogaum_and_His_Theresa - "Mr. Bocock was an altogether charming companion. Few men were so perennially delightful. The depth and variety of his knowledge of literature, ancient and modern, and of world history and contemporary affairs was impressive; and he invariably expressed his views in perfect English. No one was ever bored in his presence." http://en.wikipedia.org/wiki/Willis_Henry_Bocock - "There are no concrete answers as to the source of the name of the dish. One story goes that a Westerner came across the dish "sweetened soya sauce chicken wings" in a restaurant, and asked a Chinese waiter what that was. The waiter, who did not speak perfect English, introduced the dish as Sweet Wing. The customer misinterpreted sweet as Swiss, and the name was used ever since. However, this story may be a mere urban legend." http://en.wikipedia.org/wiki/Swiss_Wing
