AbstractOffice designers have been concerned with speech privacy for decades. One way to define speech privacy is the capability of a listener to understand, or to be disturbed by, a conversation that is taking place somewhere else in the same, or in the adjacent, office. In the nineties, the study of speech privacy has mainly been carried out in terms of intelligibility, and the speech privacy index, PI, was defined as the complement of the intelligibility (PI = 1 - I). This work will focus on the speech privacy of enclosed offices. In that case the main parameters involved are the source speech, the transmission loss of the separating wall, and the background noise in the receiving room. A statistical model will be developed, based on the Speech Intelligibility Index, to analyse PI as a function of the above mentioned parameters in order to estimate the relative importance of each one of them to the privacy problem.
