An input device should be natural and convenient for a user to transmit information to a computer, and should be designed from an understanding of the task to be performed and the interrelationship between the task and the device from the perspective of the user. In order to investigate the potential of speech input as a reality based interaction device, this paper presents the findings of a study that investigated speech input in a VR application. Two independent user trials were combined within the same experimental design to evaluate the commands that users employed when they used free speech in which they were not restricted to a specific vocabulary. The study also investigated when participants were told they were either talking to a machine (e.g. a speech recognition system) or instructing another person to complete a VR based task. Previous research has illustrated that when users are limited to a specific vocabulary, this can alter the interaction style employed. The findings from this research illustrate that the interaction style users employ are very different when they are told they are talking to a machine or another person. Using this knowledge, recommendations can be drawn for the development of speech input vocabularies for future VR applications.
