Supplementary material for "Effects of hand postures on voice directivity"

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.
