Voice for Good


In the fast-moving and volatile world that we live in today, the ability to access up-to-date, interactive information is key. For the 3.8bn people who have no access to the internet and are living in resource-poor communities in developing countries, the prospects of moving out of poverty are diminished by this lack of access.

Voice for Good’s mission is to use the world’s most widely-available instant communication technology – a basic phone call – to unlock the benefits of web-based services for the world’s poorest and most marginalised people.

Whilst there are some great efforts being made by large companies like Facebook, Google and SpaceX to close the global digital divide, the Broadband Commission’s “ambitious” target is to reach just 35% affordable user penetration by 2025 in “Least Developed Countries”, with these efforts accounted for. With not just access but also relevance, literacy, power and training being key factors in adoption, the global population who stand to benefit from VfG’s approach is and will remain significant for the foreseeable future.

Vocodo is VfG’s voice-powered tech platform, supporting 15+ languages and allowing users to communicate with services using natural voice. Users access Vocodo by dialing a local-rate phone number in their country and then communicate with services that are powered by modern, web-powered systems. Tailored user experiences are delivered by Vocodo’s personalisation layer whilst also building a comprehensive data-view of users.

2 proof-of-concept services have been built to date (translation and medical triage), with potential future services in areas of education, agriculture, access to existing NGO services, finance, entertainment, ecommerce and much more.


The technology

The Vocodo platform brings together a number of best-in-class technologies in novel ways and combines them using VfG’s proprietary code to enhance the user experience. Speech recognition and synthesis technology are provided by Google, IBM, Amazon and Microsoft’s APIs with the platform deciding which provider to use at any time based upon the caller and context. It also dynamically provides ‘hints’ to the APIs to increase the probability of correct recognition based upon the context. For natural language processing, translation and service-specific tasks like medical triage, we use other 3rd-party APIs. In terms of handling the incoming and outgoing audio connection with end users, Vocodo works with both large cloud communications providers like Twilio and directly with local providers in countries like Kenya. On top of this, Vocodo tracks every user-interaction (either anonymised or associated with a user) across the platform and populates the internal database, enabling elements of personalisation for our users, for example saving default selections and skipping T&Cs that a user has recently agreed to.
