Peter OK, great. I have two talks, one is more for ITS people (impact of speech versus text on learning gains and other performance measures), and one is more for NLP people (use of prosody and lexical information for recognizing student emotions, to ultimately trigger dialogue adaptation). Which would be better? On Wed, 18 Aug 2004, Peter Brusilovsky wrote: > Thanks, Diane, > > Oct 15 is yours.

Litman To: dmurr@mail.sis.pitt.edu Cc: Diane J. Litman Subject: abstract Experiments with ITSPOKE: An Intelligent Tutoring Spoken Dialogue System While human tutors typically interact with students using spoken dialogue, most computer dialogue tutors are text-based. To evaluate the utility of adding spoken language capabilities to dialogue tutors, we have developed ITSPOKE, a speech-based dialogue system that uses the Why2-Atlas text-based tutoring system as its ``back-end.'' In ITSPOKE, a student first types a natural language answer to a qualitative physics problem. ITSPOKE then engages the student in a spoken dialogue to provide feedback and correct misconceptions, and to elicit more complete explanations. In this talk, I will first describe ITSPOKE. I will then present the results of two experiments comparing typed and spoken tutoring dialogues, one in a human-human scenario, and another in the ITSPOKE human-computer scenario. Our main results are that changing the modality from text to speech caused large differences in the learning gains, efficiency and superficial dialogue characteristics of human tutoring, but for our first version of ITSPOKE, it made less difference.

I assume I should bring my own laptop? The cart that will be installed has a computer, a projector, and speakers. You could use this computer or bring and connect your laptop. It would be wise to come a bit earlier to make sure that the technology works. The welcome coffee starts at 10:40. If you come at 10:35 you will have time to give the job of checking the system to one of our GSA. Donna, could you ask Jace to get the cart tomorrow at 10:30, not 11 and send a lab assistant to help with the sound?
