Laboratory voice data entry system

We have assembled a system using a personal computer workstation equipped w ith standard office software, an audio system, speech recognition software and an inexpensive radio-based wireless microphone that permits laboratory workers to enter. or modify, data while performing other work. Speech recog nition permits users to enter data while their hands are holding equipment or they ale otherwise unable to operate a keyboard. The wireless microphone allows unencumbered movement around the laboratory without a "tether" that might interfere with equipment or experimental procedures. To evaluate the potential of voice data entry in a laboratory environment, we developed a prototype relational database that records the disposal of radionuclides an d/or hazardous chemicals. Current regulations in our laboratory require tha t each such item being discarded must be inventoried and documents must be prepared that summarize the contents of each container used for disposal. u sing voice commands, the user enters items into the database as each is dis carded. Subsequently, the program prepares the required documentation.
