RADC/EEV Diagnostic Rhyme Test System Improvements

Abstract

This report fully documents the current Diagnostic Rhyme Test (DRT) System used at RADC/EEV for the test and evaluation of the intelligibility of digital voice communication systems. All improvements to this system are presented in detail. This report is structured to serve both as a guide for the use of the DRT system and as a reference for modification of the software or for conversion of the software to another facility. This report documents four special projects that are associated with the DRT system. A modification to the DRT that allows for the measurement of the intelligibility of systems that are heavily affected by transmission drop-outs or bursts of transmission errors is presented. A method and system for performing the DRT at Field sites is given. This method includes software for the presentation of test words to the speaker and the collection of listener response data. The ability to repeat partial sections of a test is provided. The procedures used for the generation of the DOD Digital Voice Processing Consortium DRT/DAM Digital Master Library are given. This master library of source material for DRT/DAM testing of voice communication systems is discussed. Contents of the library are provided.
