We describe ongoing work to integrate statistical user models in the usability engineering process of spoken dialogue systems. The idea is to gener- ate user dialogue actions up to the spoken utterances in response to system ut- terances and directly feed them to the system under test. The underlying user models are derived semi-automatically from dialogue corpora. All simulated in- teractions are logged and a usability profile is derived from the log files, using HMMs to continuously estimate user judgments.
