INVESTIGATION AND EVALUATION OF THE GEL SPEECH SYSTEM TEST SET
Abstract
Mathematical models of the articulation scores of an untrained and a fully trained team of listeners were developed. The maximum variance of the trained team was found, and the precision of the results was computed. An investigation was made of the GEL Speech System Test Set's capability for providing a measure of the degradation in intelligibility that occurs when a voice signal is passed through a noisy speechcommunication channel. The test set's measure of intelligibility was compared with that of a trained articulation team, and calibration curves were established for a variety of interference conditions. The validity of the test set design principle was verified for particular interference types, and the ability of the test set to perform in accordance with that design principle was determined. The inherent test set limitations are briefly discussed, and the possible extension of the test set's capability for ranking communication systems for other interference conditions is summarized.
