The Diagnostic Rhyme Test (DRT):An Air Force Implementation,

摘要

The Diagnostic Rhyme Test (DRT) for intelligibility of voice communications systems has been implemented at the Air Froce Voice Processing Facility, Hanscom AFB, Massachusetts. This report describes the recruiting and training of listeners and the usage of software to score the DRT. In addition, performance of the in-house DRT is described. It is concluded that the in-house DRT is an economical measure of intelligibility that yields highly reliable resutls and adequately discriminates small differences in intelligibility. It is further concluded that in-house DRT results are comparable to those obtained by a contractor. (Author)
