Résumé

This paper describes the process and problems of developing a new measure of architectural speech security. Such a measure is required to more accurately rate the probability of a listener outside a room being able to overhear conversations from within the room. Previous work has considered various levels of speech privacy, where some speech is intelligible (Cavanaugh et al., 1962). However, speech security usually implies that none of the overheard speech is intelligible, or in some cases it is not even audible
