Below are the Powerpoint slides presented at the one-day event based on the Stanford course, Communication 369, "Experiments in Voice User Interfaces." A more elaborate web site will be developed in the coming months, including access to the actual questionnaires, sample experiments, etc..

Clifford Nass and the students of Communication 369 are currently working on a book manuscript, Voice Interfaces: Social Psychology and Design, that will describe this work in more detail.
