How Speech Recognition can be Implemented in a VR Helicopter Door-Gunner Simulator : A Qualitative Study

Sammanfattning: This study investigates the possibilities for implementation of speech recognition software in order to ease the usage of a Virtual Reality Simulator. The Pitch Door-Gunner simulator is described followed by a general discussion about simulator and simulator environments. Previous research and theories regarding speech recognition technology are presented, and relevant aspects for training effects such as stress are accounted for. Interviews are conducted with military personnel in order to better grasp how the simulator is actually used and how it can be used to elicit learning. An implementation with a subsequent feasibility test is conducted to investigate practical limitations and give more insight into the possibilities regarding the usage of speech recognition in the simulator. The results show that it is feasible to use speech recognition software to control simple functions, more elaborate functionality requires further research. Furthermore, the study discusses which functions would be favourable to control considering the pros and cons of speech recognition. It is suggested that speech recognition can be important as a tool to make usage more convenient and as a tool to support the instructor, for example, by bookmarking certain segments of training for later review with the help of voice-commands.
