This article proposes to sketch a methodological basis for an intermedial analysis of voice in its sonic, performative and embodied, semantic and audiovisual dimensions. The voice is at once an individual acoustic "identity card" of the singer and a means of linguistic expression, as well as being in a more or less metaphorical way used to describe strategies of representation in the political and semiotic sense of the word. Thus, analysing the voice as understood here is not only about singing, but as well developing the category "voice" for analysis itself.
