The Reception of Repeated and Overlapping Speech Patterns
John W. Black · The Journal of the Acoustical Society of America · 1955
Recorded nonsense syllables (CVC) were fed to the headsets of listeners via two channels simultaneously, a direct line and a line that introduced controlled amounts of delay from 0.130 to 0.33 second. The amount of delay was varied in 0.03-second increments and the effect of this variable upon the reception of the syllables was measured. Although the intervals of delay affected the reception scores differentially, no time of delay in the double presentations yielded intelligibility scores that were higher than the scores obtained through a single, direct playback of the stimuli.
