Either has two different pronunciations in modern English. The pronunciation IPA: /"i;D@/ prevails in American English, and is the pronunciation of the majority of English speakers. The pronunciation /"aIð@/ is associated with British English and Canadian English, but it is not universal in either place or in Australian English and other dialects that take their lead from British English. It is also found in the U.S., especially in New England, although many Americans will regard it as an affectation.
An Ira Gershwin song, Let's Call the Whole Thing Off, opens with the words "You say /"i;D@/ and I say /"aIð@/", and concerns a couple who lament the difficulties in their relationship by pronunciation differences (and the different social backgrounds which they imply). These differences between the two lovers could be the reason to call off the relationship. But they can't stand the thought of being apart so the singer will compromise for love.

CHAV noun (BrE, slang) a young person, often without a high level of education, who follows a particular fashion. Chavs usually wear designer labels, and if they’re girls, very short skirts and stilettos. Chavs still see branded baseball caps as a status symbol and wear them at every opportunity. The term is similar to America's 'white trash' stereotype.
EXAMPLES:
noun: There are always loads of chavs hanging round the shopping centre.
adj. [only before noun]: The bus was full of chav kids and chav girls with their big gold jewellery.
In Britain there are many words to describe people from this social group, and they are often limited to a particular town or region. Other words with a similar meaning to chav are townie, scally, ned and charver. The word chav has become common in southern England, and is generally thought to come from Chatham girls (Chatham is a town in Kent.) Some people think, however, that the word comes originally from the Romany word chavo (boy), which is also the origin of the Spanish word chaval.
