This article compares the most significant advances made by FrenchDiscourse Analysis (DA), developed by a team of researchers underthe pioneering leadership of Michel Pêcheux, with the ‘polyphonictheory’ developed by Oswald Ducrot. While DA develops animportant framework for discourse analysis which firmly situatesdiscourse in a broader context of social relations, Ducrot’s approachis not interested in the concepts of ‘ideology’ and ‘power’. If thiscrucial difference is taken into consideration, Oswald Ducrot’spolyphonic theory may be used by discourse analysts as oneapproach among others for investigating the interplay between the‘voices’ of discourse.
