Abstract

The authors conducted concurrent experiments employing subjective evaluation methods to examine the effects of the manipulation of several sound system design and optimization parameters on the intelligibility of reinforced speech. During the course of these experiments, objective testing methods were also employed to measure the Speech Transmission Index (STI) associated with each of the variable treatments used. Included in this paper is a comparison of the results of these two testing methods. The results indicate that, while STI is capable of detecting many effects of multiple arrivals, it appears to overestimate the degradation to intelligibility caused by multiple arrivals with short delay times.
