Experiments in the Psychology Department of George Washington University suggest the possibility of constructing sub-languages of English which can accelerate communication. "Quickspeak," a restricted redundancy language, eliminates from natural language those linguistic cues which are reconstructable from those that remain. Principles for constructing a variety of Quickspeaks which have a wide range of communication properties are being formulated in these experiments. In a second approach to time-reduction in speech, messages are compressed in time by means of a "Tempo Regulator" device. Research (by Orr and Friedman at the American Institutes of Research) has shown that with training in "speed listening," a person can learn to hear 475 words of compressed speech per minute. (An average speech rate is about 175 words per minute.) One aspect of the present research is a study of the relationship between the syntactic structure of the sentences in which information is packaged and the ease of storing the information in temporary memory. (Evidence suggests that for information to be stored in long-term memory, it must first be effectively stored in temporary memory.) The value of such a memory-optimizing language may go far beyond its application to speed speech or Quickspeak since its principles could be used in more ordinary communication. (AMM)
