dc.description.abstractThe goal of this project is to develop a top-level design for an automatic speech recognition system that identifies the type of emitter report given by Electronic Warfare (EW) operators during their shipboard duties. The verbal report is one of the overt actions used to measure an operator's task proficiency. The operational requirements and maintenance concepts are defined in parallel with a feasibility study of computerized speech recognition systems. A functional analysis of the operator's task actions and the requirements for speech recognition in this task situation identify the elements necessary for the speech recognition system. To determine the functional allocation for the speech recognition system, a study was conducted to determine the baseline accuracy of a commercial system. It was determined that the PC-based speaker-independent recognition system was capable of identifying the type of emitter report given by the EW operator. The accuracy of the system was greater than 75% so the design will continue with the PC-based system used for the automatic speech recognition function.en
