This paper is related to three-dimensional (3D) audio signal processing for virtual spatial audio conference applications. The core idea is to provide users of a virtual spatial audio conference with recommendations for the optimal spatial layout (spatial arrangement) of participants where optimal implies maximal speech intelligibility. That is, the listener’s ability to understand speech from an individual speaker in a multi-speaker scenario is enhanced. The idea combines information of the individual’s voice together with directional audio information to estimate the speech intelligibility of candidate spatial layouts (spatial arrangement). The candidate layout that provides the best speech intelligibility estimate is then selected.
