Evaluation of Helium Speech Unscramblers under Controlled Conditions.

Abstract

In order to evaluate the effectiveness of HeO2 'unscramblers,' a four-part project was undertaken: To evaluate available unscramblers on-line; to test them off-line; to develop a standardized off-line test for the evaluation of all types of uncramblers; and to establish guidelines for the development of optimum equipment of this type. The report provides the results of two evaluations of a number of unscramblers. The first evaluation was conducted 'on-line' during the training of SeaLab-3 aquanauts at EDU; it was followed by an off-line (bench) test. Also described is a test consisting of 57 word-lists that have been developed for standardized off-line evaluations of electronic aids to speech communication in HeO2/P environments.
