Speech Recognition Software; An Alternative to Reduce Ship Control Manning
Abstract
This study identifies factors affecting the performance of commercial-off-the-shelf speech recognition software (SRS) when used for ship control purposes. After a review of research in the feasibility and acceptability of SRS-based ship control, the paper examines the effects of: * A restricted vocabulary versus a large vocabulary, * Low experience level conning officers versus high experience level conning officers, * Male versus female voices, * Pre-test training on specific words versus no pre-test training. Controlled experimentation finds that: * The experience level of a conning officer has no significant impact on SRS performance. * Female participants experienced more SRS errors than did their male counterparts. However, in this experiment, only a limited number of trials were available to assess a difference. * SRS with restricted vocabulary performs no better than SRS with large vocabularies. * Using the software "correct as you go" feature may impact software performance. Following the user profile establishment, individual user training on two specific words reduces error rates significantly.
