Language revitalisation gives voice to those who participate in it. But it is not always clear whose voice the participants make heard. It is also not straightforward who hears and wants to listen to the voices that are raised during language revitalisation. In this article, we present a language educational programme which aims to give voice to the participants of the Moldavian Hungarian (also called Csángó) language revitalisation in North-East Romania. Applying the Goffmanian participation framework, we demonstrate that the participants of the programme collaborate in giving voice to a Csángó-speaking figure while covertly performing different roles. Drawing on our linguistic ethnographic research, we point out how this institutionalised participation framework promotes the achievement of one of the objectives of language revitalisation: the restoration of past language practices. Nevertheless, it also creates an obstacle to another: to the way that the speakers of this language can have a voice worth hearing. The analysis highlights the tensions of institutionalising a participatory framework in language revitalisation, which aims to produce the belief in a Csángó figure representing the essential link between language and (national) community.
