Utilizing technology which exists in-house woodside design associates inc. (wda) will combine speech recognition and speech synthesis technologies into a compact data input device capable of being mounted on a hard hat or into a hand-held unit. This technology, which has been tested by an independent lab under a development contract from mcdonnell douglas corporation consistently withstands a o dB signal to-noise ratio. Not reliant upon the industry standard of markovian pattern matching, it will tolerate both high level ambient noise and intermittent noise. Additionally all but the most severe regional accents can be recognized and face mase muffleing vocal changes due to stress and the common cold will remain transparent. The system is truly speaker independent accepts continuous speech responds in real-time and for this application will be capable of a 100 word vocabulary. Formatting translated data and rs-232 interface are consdered standard. The synthesis technology will provide verification with a realistic "human" sounding voice.
