The report describes an Automatic Intelligibility Test equipment AITE which automatically measures the word intelligibility of a digital voice communication link. The system consists of a Nova 820 mini computer, AID converter, teletype unit ASR-33, tape recorder, high speed paper tape reader and punch set, and the phoneme test sequence. The phoneme test sequence is recorded on audio tape which played through the equipment being evaluated and then into the AITE. A set of forty phoneme correlation masks were designed using phoneme pattern matching in conjunction with listening jury statistics. The AITE evaluates the phoneme test sequence using speech correlation techniques to determine the word intelligibility. Author
