Gurgaon Idol: Running a talent competition on IVR and community radio

As part of his PhD research, Zahir helped Gurgaon ki Avaaz run a singing talent hunt on community radio and IVR.

We experimented with two kinds of IVR voting interfaces — best of two, where a pair of songs were presented the callers had to tell us the better on.

It was a great experience and told us how to enable such formats on IVR. Read the full paper dev2013v10.
