Helium Speech Investigations.
Abstract
The basic objective of the work was to continue evaluations of and achieve further improvements in the Singer-Kearfott unscrambler technique. The report summarizes briefly the work completed. Two major new topics are reported, an investigation of the formant shift in neon-air, and a miniaturization study of the existing unscrambler configuration. Functional descriptions and design data are presented on two miniaturization approaches for a helium unscrambler, one using an all-digital circuit and one using a novel analog memory. The analog approach is attractive, requiring fewer circuit elements and less power drain than the digital type. (Author)
