Authors: Brachmanski, Stefan

AES Convention 112 · Paper 5588 · April 2002

Abstract

The paper describes the new measurement system and method of speech transmission quality evaluation called "modified intelligibility test with forced choice" (MIT-FC). The MIT-FC method provides fully automatized measurement of speech intelligibility of rooms. The listener's task is to selected on computer monitor which of alternative utterances presented him visually was spoken. The computer's program automatically calculates speech intelligibility and the factor of speech quality. The results are compared with RASTI measurements. The measurement system is based on the local computer network and enables to carry out measurements in several places of the room (depending on the size of the local computer network).
