Abstract:

Studies are conducted by the Combat Communications Task in voice-radio communications techniques and overall performance of personnel involved in communications operations. An experiment was designed to determine the effects of 20 different transcription methods on the performance of 12 Army enlisted men in transcribing word lists received at 4 signal-to-noise levels. Three aspects of communications procedure were examined listening to the message, writing the message as it was heard, and using a previous transcript of the message as an aid in re-listening and re-transcribing. Significant improvement in performance was obtained when subjects both listened to and wrote the word lists more than once. Performance did not improve at any signal-to-noise ratio when listening to a given word list more than once before writing the transcript nor when the subjects used a first or second transcript as a reference aid in retransribing a word list. Conclusion was that although the actual obsolute gain in accuracy was low, there was sufficient improvement to warrant repeated listening and repeated writing of messages when reception conditions are below the marginal level of channel communications.
