Studies of Voice Communication in the Navy: Sentence Predictability
Abstract
The predictability status of several sentence lists was evaluated for use in the testing of hearing of Navy personnel. One hundred and eighty normal- hearing subjects divided into six groups, listened to three sentence lists under various predictability conditions. The following results were obtained: (1) It was necessary to remove between 20 to 25 words for Sentence Lists B and D, respectively, before obtaining a significant score reduction. These lists were found to be predictable and quite similar with regard to their response to key- word elimination. (2) Considerably lower scores were obtained for List C than those obtained for Lists B and D. Furthermore, increased degradation through increased key-word elimination did not significantly affect the predictability scores. It was concluded that List C is considerably less predicable than lists B and D. (3) The error curve for a Synthetic Sentence List was found to be extremely low and relatively flat, suggesting that this group of sentences has a negligible predictability value.
