Africa’s rapid digital revolution, especially through mobile communications, combined with radio’s popularity, offers a significant opportunity for engaging and analysing citizens’ voice quickly and in hard to reach places. The Africa’s Voices Foundation is a non-profit start-up growing out of interdisciplinary research at Cambridge's Centre of Governance and Human Rights. It combines social science insights with new approaches to data analytics, and is already supporting governance and development actors in a range of contexts. This presentation charts its genesis and its future ambitions.
