People of different ages have diffe

People of different ages have different accents and this is because change constantly occurs in the language. The accent of a community changes alongside social and political change but also because the sounds of speech make up a system that is self-regulating and constantly in flux. We can say that change can be external (social/pollitical) or internal (linguistic/phonetic). Changes usually enter a dialect through the speech of teenagers or pre-teens who desire to express their identity independent of the previous generation.
