I have a fairly thick Boston accent if I speak normally. I try to slow down and enunciate though. I have nothing against the accent, I just prefer everyone doesn't immediately know where I'm from within 5 minutes of meeting me.
Actually no, in each language there is one location at least that is considered accent-less. Basically they determine a standard as the 'pure' version of a language and then any differences around that is considered an accent. For instance it's Akron, Ohio for American English that is considered to be accent-less. Accents are usually defined by region or social class the issue is how large of a region you consider before you claim it's an 'accent'. Is a country of origin small enough to declare as an accent or is it a particular city within that country, since that isn't standardized the colloquial sense of the term 'accent' is largely subjective. Pretty much anybody from a foreign country speaking a non-native language will have a roughly identifiable location, but odds are to a native speaking they're not going to be able to identify a specific town whereas some towns within a native speakers language can sound fairly unique. Clearly the scope of saying somebody has an Asian accent (typically trouble with "l" and "r" is a far cry in specificity compared to Boston.I'm sure I do to someone, doesn't everyone?
