The Wizard-of-Oz simulation technique has been used in the development of the dialogue model for a spoken language dialogue system. The paper focuses on the trade-off between system naturalness and the technological constraints imposed by the speech recogniser. The constraints enforce a strongly system-directed dialogue. Phrases and subjects influence the trade-off whereas voice distortion apparently does not.
Keywords: Spoken language dialogue systems, Wizard-of-Oz, dialogue model.
