Using the Audiopedia approach we are able to provide health education even to remote and marginalized populations. Take for example the Aka. They are a nomadic Mbenga pygmy people living as hunter-gatherers in the dense rainforests of the Western Congo Basin in Central Africa. The Aka people are vulnerable individually and as a community. They are geographically isolated, illiterate, have no written language and no access to social services. So how can we make sure that they can acquire vital health knowledge?
