Evaluating Responsiveness in Spoken Dialog Systems

Ratings of user satisfaction, although fairly easy to elicit for today's spoken language systems, can be more elusive for systems which operate at near-human levels of performance. This problem can be alleviated by adding a 're-listening' phase before eliciting judgenients: in this phase the user listens to a recording of himself interacting with the system while consulting a transcript of that interaction This technique allows more sensitive judgements of system quality by avoiding problems arising from attention limits.
