Internet technologies – like social media platforms and discussion forums – have transformed how people communicate with each other. In addition to improving access to information, news, and entertainment, they have impacted governance, politics, civil society movements, crisis response, marketplaces, and healthcare, among other parts of our lives. Although concerns regarding data misuse, privacy breaches, and overuse have grown recently, these technologies are continuing to soar, mostly among literate, urban, and connected communities, all across the world. However, despite their promises (and pitfalls), these technologies currently exclude billions of people worldwide who are too remote to access the Internet, too low-literate to navigate the mostly text-driven Internet, or too poor to afford Internet-enabled devices. This chapter presents the innovation, implementation, and adaptation of voice forums that have evolved over the last two decades, discusses challenges that plagued their growth, and highlights ingenious solutions that were used to address their pain points.
