The repository contains measured voice directivities while performing static hand postures. The directivities were measured in the anechoic chamber of TH Köln applying a surrounding spherical microphone array, which has a diameter of 2 m and a shape of a pentakis dodecahedron. The datasets were stored in the SOFA-format and include two measurements for each of the 13 subjects. Each subject's dataset contains directivities of the following conditions REF: Reference measurement - normal articulation of an [a]. HFM: Holding a hand in front of the mouth while articulating an [a]. CAM: Cupping the hand around the mouth while articulating an [a]. The .pdf file contains general information on the voice directivity files in the SOFA format information on the indices and names of the SOFA-files Polar plots of the directivity patterns in third-octave bands The .zip files contain voice directivity patterns in the SOFA format sampled on the sparse measuring grid voice directivity patterns in the SOFA format upsampled to a dense grid The Matlab script provides an example reading a dataset, performing spatial upsampling if required, and creating some basic plots.
