Improving Query Reformulation in Voice Search System
During online search, users frequently modify the existing query to get better results. For voice search users, the system error is a second reason of query reformulation. In keyboard system, query reformulation usually involves partial modification which is not well supported by the current voice search systems. In this proposal, I aim to develop a set of voice commands which will improve the user experience in query reformulation during voice search. The study will include four phases. Firstly, a survey will be used to collect the user's perception of the current voice search system. Secondly, an experiment will be performed to find out how the users would like to communicate with the system. Thirdly, a set of voice commands will be developed based on the findings of the second phase. Finally, another experiment will be used to test the effects of the voice commands.
