Experiments in Auditory Perception With an Analog Model for the Ear.
Abstract
The model representation for portions of peripheral, ascending and central mechanisms in auditory processing was extended so as to better match human behavior and structure. The improved model was needed to implement the fundamental purpose of the research, namely, developing better ways for achieving speech bandwidth compression. Of particular interest and importance were observations of the fluctuations in analog ear patterns at glottal rates. Earlier techniques with analog ears and spectrum analyzers which smooth over these fluctuations are rather misleading as to the significance of extracted measures. Various algorithms for realizing bandwidth compression in which voice pitch may or may not be retained are developed. The question of bandwidth compression is closely related to word recognition and other problems of practical significance. The presentation is sufficiently generalized to include these other possible applications. (Author)
