AbstractThe intelligibility of speech recordings made in rooms and other spaces is affected by factors such as reverberation, background noise, the distance between the speaker and the microphone, and the properties of the microphone system. This paper presents results of tests evaluating the intelligibility of speech recordings made with a variety of microphone systems under controlled conditions. Test speech sentences were recorded and the intelligibility of the recordings was determined by a subjective listening test. In addition, STIPA, a form of the Speech Transmission Index intended to predict intelligibility for electro-acoustic systems, was determined for each recording condition.
