Abstract
In this chapter, we will describe two other applications in which we have attempted to measure the speech intelligibility using the intelligibility test defined in earlier chapters. One application is the use of speaker-dependent maskers to mask sensitive spoken dialogue from leakage. The intelligibility of the speech with the proposed speaker-dependent maskers were measured using the JDRT. In the other application, we used a highly-directive parametric speaker array to provide audio guide in a museum or an art gallery, for instance, where the audio guide needs to be focused to a narrow area in front of the display. We attempted to measure the interference of the neighboring guide speech, and measured the effect of this interference on the intelligibility of the guide speech.
