My research focuses on the use of Speech and Language Technologies to aid socio-economic development all around the world by enabling dissemination of speech-based, development-related information and communication services to low-literate telephone users; without the benefit of explicit user training. My work shows that speech-based simple entertainment services can be used as powerful motivators to induce self-training and viral spread among low-literate masses. Such services can further be used as vehicles for delivering core development services and as experimental test-beds for performing randomized controlled trials and demographic studies.
My doctoral thesis: Polly employs voice-based viral entertainment to familiarize low-literate and non-tech savvy people to telephone-based speech interfaces. Polly acts as a viral conduit for disseminating telephone and speech based development-related services to masses and to implicitly train the general population in the use of such services. In 2012 the use of Polly spread virally in Pakistan from five initial users to 165,000 users who participated in 636,000 calls, over a year. At its peak it was spreading at the rate of 1,000 new users every day. It also attracted 34,000 of its users to Polly-Jobs, a job-audio-browser.
In 2014, Polly became viral in India where it was launched in Bangalore collaboration with Babajob.com and Microsoft Research India to spread information about jobs appropriate for low-skilled workers. Polly was also successfully used in Jharkhand and Bihar in collaboration with Jharkhand Mobile Vaani to cross-sell their citizen radio-over-phone platform.
In March 2015, Polly was launched in Guinea in collaboration with the US Embassy in Conakry to spread authoritative and reliable information about Ebola. Polly and its new variant Polly-Sante' (Polly-Health) are currently live in Guinea and are receiving a sustained daily call traffic.
