Improving Speech Intelligibility in Teleconferencing by using Wave Field Synthesis

teleconferencing can be enhanced considerably with the application of spatial sound recording, transmission and reproduction. True spatial sound reproduction can be obtained with Wave Field Synthesis (WFS) which gives a sound reproduction that is independent of the listener position. Our research has shown that a significant improvement of speech intelligibility can be obtained with WFS as compared with a single loudspeaker reproduction, when there are several interfering speech signals. The improvement in Speech Reception Threshold (SRT) can be more than 2 dB, making a change in speech intelligibility from 50% to 85%.
