| Abstract: | Widespread use of videophones has been limited due to cost factors and human factors. If demands for image size and quality were relaxed while preserving the communicational value added by visual data, low end videophones may become feasible. After a review of pertinent research, we describe an experiment indicating modest visual augmentation significantly aids speech intelligibility. The results suggest several directions for further research. |
