Abstract
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.
