AbstractVarious speech privacy criteria have been proposed for use in both open-plan offices and enclosed rooms. They have been given in terms of: Articulation Index (AI), Speech Intelligibility Index (SII), and various signal-to-noise ratio values. In this paper, the results of previously published speech intelligibility tests were used to describe the relationships between the various measures in both types of office environments. Because increased speech privacy is usually assumed to relate to decreased speech intelligibility, the previous speech test results were used to interpret each criterion value in terms of the expected intelligibility of speech. The criterion values were also related to published estimates of the threshold of intelligibility.
