Human Verbal Behavior Considerations in the Design of Voice Actuated Hardware Systems.
Abstract
An experimental study was made of the verbal behavior patterns of 15 P-3C and 15 non-P-3C aviators to determine a voice command vocabulary structure to be used with machine voice recognition hardware for implementation in P-3C aircraft. Subjects were required to give a one or two-word verbal command response to a visual slide stimulus of a simulated P-3C pilot's display. There were five distinct sets of slides, each portraying a different visual presentation. The subjects received the five sets in each of three block giving a total of 15 responses per subject. The verbal response were recorded along with response latencies. Response latencies decreased for both groups as they progressed through the experiment with the P-3C group always having lower latency times. Both groups preferred using a two-word versus one-word command to describe changes on the visual display. Due to the different aviation backgrounds of the two groups, there was no uniform preference for a specific syntactic structure of the command phrases. The implications of the findings for the design of systems using vocal commands are discussed.
