This paper engages in a self-critical reflection on the limits and decolonial potential of the project advanced by the author, entitled 'grammars of listening'. In the first part, the author explores the theoretical context that frames said project, namely, the analysis of the epistemological and ethical challenges that result from the task of listening to testimonies when working on historical memory. This involves a philosophical inquiry into the concept of traumatic violence as a "colonizing" form of violence. The second part of the paper examines the extent to which the project on grammars of listening holds under the scope of a decolonial look, and proposes two possible strategies for a "decolonization of listening," namely, the invention of history and the resistance of memory.
