Abstract

The proliferation of communication devices has brought into being a host of media, including the use of voice over telephones, text in e-mail and images in faxes. As people become more mobile, they will need portable devices to access information in a timely way, whether they are in the office or on the road. The telephone is a convenient and ubiquitous device which people already know how to use, and it offers a familiar interface. But, traditional touchtone-based applications are hard to use.
