the effect of miscommunication rate on user response preferences
We report results from a small Wizard-of-Oz study investigating user responses to miscommunications in speech dialogue systems. We explore the separate and joint effects of miscommunication rate and system response to miscommunications on the likelihood that users choose to resort to direct manipulation, to repeat, or to rephrase. While we predicted that users would be more likely to resort to direct manipulation as miscommunication rate increased, our surprising finding was that users were most likely to resort to direct manipulation where communication success was least predictable, i.e., in the middle of the range, rather than at either extreme.
