This article makes a case for studying the perceptions that young people have of the ways of speaking of both themselves and others on the supposition that constructions of ambient sociolinguistic variation have an impact on the language development and use of individual language users. Such a study is particularly relevant in multilingual contexts in which differences with regard to social as well as ethnic and linguistic background may generate significantly different perceptions. In a speaker evaluation study, Swedish speech stimuli from 12 young Stockholmers were evaluated by 343 listeners from different backgrounds. The results show that young people may divide and relate to the linguistic space of Stockholm in very different ways and that they vary in their degree of accuracy regarding linguistic self-perception.
