Report on Training Studies in Voice Communication: 1. Can Intelligibility of Voice Communication be Increased by Training in Voice Technique?
Abstract
Data are given from three selected experiments to show the results obtained from training student pilot subjects in voice technique. An all of the training experiments, the criterion for evaluating results was a word intelligibility t est. Results showed that training for a period as short as two hours produces gains in intelligibility score which are greater than that for a control group by amounts which are statistically significant at high levels of confidence. Further training up to six hours showed additional improvement. Significant differences exist between training procedures, indicating a need for careful working out of most advantageous procedures. A breakdown of the data into quartiles on the basis of the initial test scores shows that the subjects who scored lowest on the initial tests make the most marked improvement.
