A multimedia speech corpus for audio visual research in virtual reality (L).

Virtual reality environments offer new possibilities in perceptual research, such as presentation of physically impossible but ecologically valid stimuli in contrived scenarios. To facilitate perceptual research in such environments, this study presents a publicly available database of anechoic audio speech samples with matching stereoscopic and 360° video. These materials and accompanying software tool allow researchers to create simulations with up to five talkers positioned at arbitrary azimuthal locations, at multiple depth planes, in any 360° or stereoscopic environment. This study describes recording conditions and techniques, contents of the corpus, and how to use the materials within a virtual reality environment.
