Abstract
The performance of spreadsheet users was compared for two modes of input to the computer—keyboard and continuous voice recognition (CVR)—for subjects classified by their decision style. In addition, the data for this experiment was compared to results of a similar experiment that used a discrete word recognition system. Dependent measures were task completion time, accuracy, keystroke count, correction count, and user confidence for spreadsheet tasks. Results, using a speaker-dependent continuous voice recognizer, showed that for both simple data input and more complex analytical problems, subjects did not perform more effectively using CVR compared to keyboard. In addition, a subject's decision style was found not to interact with CVR for an effect on performance. Compared to earlier discrete word recognition results, CVR tended to shorten the time to complete a spreadsheet analysis task.
