A Transducer/Equipment System for Capturing Speech Information for Subsequent Processing by Computer Systems
Abstract
The objective of the Phase I Small Business Innovative Research (SBIR) Program Topic A93-033, entitled A Transducer/Equipment System for Capturing Speech Information for Subsequent Processing by Computer Systems is exploratory research to parameterize the speech signal, provide benchmark measurement techniques, and to assemble a superior speech capture system while minimizing the effects of noise and interference. Human verbal response under controlled conditions and when exposed to stress exhibit quantifiable differences that when assessed by computer have direct medical monitoring application. Soldiers answer queries about symptoms, well-being, or perceived capabilities while they are performing their duties. Measures of operational performance for military tasks involving communications such as requests for fire support or sending of planned target lists are collected by computer systems. Thus, demonstrating the feasibility of this transducer/equipment system as a necessary and critical first step towards the ultimate application of computer systems to collect and analyze symptoms, moods, and performance data from soldiers in real-time in training centers, the laboratory, and the field with minimal interference to ongoing soldier activities. The algorithms developed for accurate speech capture have demonstrated immunity to a broad range of acoustic and transmission media conditions which include concentrations of acoustic noise in all anticipated regions of the spectrum significant in the human voice response band.
