The theories of language socialization highlight the fundamental role of making one's voice heard to access social practices. To better understand this idea, we will consider the notion of "voice" in terms of enunciative positioning linked to the social representations that structure the person’s social agency. After drawing up our theoretical framework, which articulates language learning, socialization, and reflexivity, we will present three types of socio-discursive positioning which, on the model of Van Langenhove and Harré (1999), take account of the interactional dynamics and the relations of power that arise and materialize there. Finally, we will hypothesize that reflective work carried out in a language class on social representations on the one hand, and positioning, on the other, is likely to improve the voice of people, acting socially in a new social and language context.
