Abstract

THIS PROJECT ADDRESSES A METHOD FOR SOLVING THE PROBLEM OF HELIUM SPEECH, AS EXPERIENCED IN DIVER-SURFACE COMMUNICATION. THE GOAL OF THE PHASE I STUDY IS TO DESIGN, PROTOTYPE, AND EVALUATE A REAL TIME HELIUM SPEECH CORRECTOR SYSTEM BASED UPON DIGITAL SIGNAL PROCESSING TECHNIQUES. HIGHER FREQUENCY FORMAT INFORMATION WILL BE EXTRACTED AND RE-INSERTED INTO THE SPEECH WAVE FORM AT AN ADJUSTED FREQUENCY, THEREBY, "RECONSTRUCTING" THE WORDS WITH APPROPRIATE FREQUENCY CORRECTION. THIS WILL BE ACCOMPLISHED IN SIX MONTHS.
