Abstract
The primary purpose of this research was to examine the effects of various input string lengths and error correction methods on the recognition accuracy and efficiency of a currently available continuous automatic speech recognition (ASR) system. The effect of sex was examined also and an estimate of the average recognition accuracy of a continuous ASR system was sought. In the entry of numerical data, the input string length of seven digits at a time proved significantly more efficient than strings of three or five. Although subjects preferred some error correction methods over others, there were no significant differences in error rates or efficiency due to the correction method used. There were also no significant differences due to sex. The average recognition accuracy of the continuous ASR system was conservatively estimated at over 95%.
