Voice Data Entry for NISTARS

The proposed effort initiates the development of a voice data entry capability for NISTARS warehouse workstations. The approach focuses on the design of the voice interface for a single workstation type, at the level of the human/machine dialog. The design process will be driven by two principal concerns: controlling the impact of recognition errors on interface performance and ultirnately on worker productivity; and integrating secondary, voice-related interface activities with worker production tasks. The detailed structure for information exchange across the voice channel specified in the design will define the capabilities and limitations of the fully implemented NISTARS voice data entry system. The completed design will include variants to encompass visual and auditory feedback, design options which drastically alter st mctural choices. A plan will be developed for implementation of the voice data entry system as designed. Based on the performance implications of the design and the projected implementation and maintenance costs, a cost benefit assessment will be performed .
