Abstract : This report covers the progress made and the conclusions reached during the first six months of effort on the development of an automated speech intelligibility test. The literature in intelligibility testing has been surveyed and evaluated. Six of the most common intelligibility tests have been compared in terms of their materials, employment of speakers and listeners, validity and reliability of results, and potential for automation. On the basis of theoretical considerations and well-known empirical findings, it is concluded that the requirement for a highly efficient and reliable automated test procedure can best be satistifed with a multiple-choice test in which the set of possible messages is known to the listener.
