This chapter seeks to explore the many meanings attached to ‘voice’ in research, with a particular emphasis on the different modalities voice can have in the field of inclusive disability studies. The interpretation of the six different perspectives of voice is based on the framework of Lawrence-Lightfoot and Davis (1997) and is contextualized within the work and engagement of the self-advocacy network in Flanders. The combination of these six aspects of voice led to the construction of a particular research design where voice is manifested through the chosen methodology, the various roles and various selves of the researchers and the subjects, the research tools and analysis. Drawing on the ideas and insights from a research project about political participation of persons with an intellectual disability in the self-advocacy network, tensions in the research process are explicated and research choices are discussed.
