The Use of Interactive Voice Systems to Improve Multiple-Task Performance.

The primary purpose of this contract was to examine the effect of voice generation and recognition systems on dual-task performance although three other research efforts on complementary topics also were investigated. This report is divided into four sections. The first section provides background information for the first experiments conducted under this contract. The second section describes each of the six experiments examining the effect of voice generation and recognition systems on dual-task performance and summarizes their results. The third section briefly discusses three other research efforts performed on this contract in support of current activities at the Naval Biodynamics Laboratory and the Naval Aerospace Medical Research Laboratory. The last section of this reports lists the products of the contract.
