Recent Progress on the VOYAGER System

Introduction The VOYAGER speech recognition system, which was described in some detail at the last DARPA meeting [9], is an urban exploration system which provides the user with help in locating various sites in the area of Cambridge, Massachusetts. The system has a limited database of objects such as banks, restaurants, and post offices and can provide information about these objects (e.g., phone numbers, type of cuisine served) as well as providing navigational assistance between them. VOYAGER accepts both spoken and typed input and responds in the form of text, graphics, and synthesized speech. Since the last meeting, we have made developments to VOYAGER that have had an impact on the usability of the system.
