International development and HCI practitioners recognize the importance of hearing from those who are disadvantaged in decision-making. However, the voices of marginalized communities for whom development interventions are intended remain little heard. This research investigates how to incorporate community voice (CV) into project commissioning. It demonstrates a holistic understanding of top-level decision-making processes and how to meaningfully capture CV, including informed consent, for project development. It critically conceptualizes CV and outlines its benefits through a framework for effective and sustainable project development. More broadly, it extends our understanding of incorporating CV in project, program, and policy decision-making for international development.
