THE EFFECTS OF PRE-EMPHASIS, PEAK CLIPPING, AND DE-EMPHASIS ON THE INTELLIGIBILITY OF SPEECH IN NOISE.

Abstract

The experiment reported here was designed to investigate the effects or pre-emphasis, various amounts of peak clipping, and de-emphasis on speech intelligibility under various conditions of noise before processing the speech and in the listening field. Results indicate that all of the variables, operating singly, two at a time, and three at a time produce small but significant differences in articulation scores. These differences may be summarized in answer to the four principal questions of interest for the investigation. (Author)
