Web for Regreening in Africa (W4RA)• Knowledge sharing issues – Distances between rural communities in Sahel – Infrastructure and access • Commonly: no electricity, no computer, no internet • But: mobile and radio – Lack of relevant content • Literacy and education – Languages 2
Can the Web (be made to) meansomething for knowledge sharing evenunder very constraining conditions?No internet, no computer, no electricityMultitude of languages, levels of literacy
Aim: integrate Web with mobile access & voice services• service development toolbox, field deployment in Africa & make a sustainable business out of it 5
Voice-based services in a rural African context• Integrate local community radios and mobile ICT for knowledge sharing• Better support and integrate local languages in voice-based services – Development of appropriate speech elements (text-to-speech and Speech recognition)• Develop a free and open source toolbox for local developers.• Investigate self-sustainability – Develop appropriate business models – In collaboration with local communities.

Audio communiqué• Audio communiqué generated by concatenating prerecorded phrases – Each radio host uses own voice (!)• Text-to-speech where possible• Currently only for French• Audio quality is an issue

Research questions• Q1 [immediate]: Can the Web (be made to) mean something for knowledge sharing even under very constraining conditions? – No internet, no computer, no electricity – Multitude of languages, levels of literacy• Q2 [Web future]: Can we have a Web of Speech? – After all, human communication: talking >> writing
