We have used text, graphics and non-speech audio to tutor new users in a spoken dialogue system. The guidance is given by a software tutor, a software component that interactively tutors the user. Four different variations of tutoring were implemented and experiences were collected from user tests in order to gain insights into these tutoring concepts. Real-time visualization of speech interaction with comic book style balloons and structured guidance were received well while various other methods received mixed acceptance.
