Abstract

In this chapter, we will describe the application of the proposed Japanese DRT to the measurement of intelligibility of localized Japanese speech in virtual three dimensional environment. Speech is localized to the specified location by convolving with the head related transfer function, which is the transfer function of the path between the source and each of the listener’s ear. We have been attempting to use speech localization to place many of the potential speech sources at distant locations within the virtual space to maintain the localized speech intelligibility, while preserving the “presence” of the other audio sources. The intended applications include multi-party audio conferencing, and augmented audio reality applications that mix localized speech on top of actual acoustic space.
