Speech intelligibility with various head-related transfer functions: A computational modeling approach

Abstract

Speech intelligibility is known to be affected by the relative 1 spatial position between target and interferers. The benefit of a spa-2 tial separation is, along with other factors, related to the head-related 3 transfer function (HRTF). The HRTF is individually different and thus, 4 the cues that improve speech intelligibility might also be different. In 5 the current study an auditory model was employed to predict speech 6 intelligibility with a variety of HRTFs. The predicted speech intelligi-7 bility was found to vary across HRTFs. Thus, individual listeners might 8 have different access to cues that are important for speech intelligibility. 9 a)
