How can tangential acceleration from a radial force be explained?

A mass is attached to a rope, and put into a circular motion. If I pull the string from the center, the tangential speed of the mass will increase (by conservation of angular momentum). I am applying a force only in the radial direction, so how can the tangential velocity increase if there is no tangential force?
