From 1994-1997, members of the staff at Sensimetrics Corporation and a group of academic consultants created a series of computer-based instructional units in speech science. The resulting CD-ROM [1] was released in 1997 as Speech Production and Perception I. Participants in the project had to devise models used to explain and demonstrate the subject matter. In addition, academic researchers needed to learn to communicate their ideas and understand those of programmers and graphic designers who had no prior knowledge of speech science. The project was financed by grants from the U. S. National Institutes of Health. Despite our planning efforts, the work took more time than we expected, and cost more money than had been provided by our grant. However, Speech Production and Perception I has been well-received by instructors, is increasingly adopted for class use at universities, and is now being distributed internationally. Work on this course has led to development of computer-based teaching materials for other subjects, for which we have retained the staff and further applied the capabilities developed during this project.
