Abstract
The article addresses the role and being of the voice, and its relation with the echo in two contexts. We start with Plato’s cave myth and the dynamic between the interior and the exterior of the cave. Then we look at the relationship between the voice-echo and the exterior. The exterior is analyzed from a series of literary, musical, and cinematographic works. The constant and guiding line, how independent the voice is; its articulation with the speaking subject; its autonomous possibilities and its plural richness.
