Spectro - Temporal Modulation Transfer Functions and Speech

Neural Correlates of Spectral, Temporal and Spectro-temporal Modulation

DEDICATION I would like to dedicate this thesis to my Director and Program Coordinator Dr. Robert Frisina Jr. who has encouraged me and stood by my side in my tough times and to my parents, brother and soul-sister, who have been my four pillars of support through all the high and low tides in my life. ACKNOWLEDGMENTS I would like to express my heartfelt gratitude to my major professor Dr. David...

Modeling spectro-temporal modulation perception in normal-hearing listeners

The ability of human listeners to detect and discriminate spectro-temporal ripples in sound has been shown to be correlated with speech intelligibility performance in several conditions. Thus, if a model would be able to account for the spectro-temporal processing limits in the auditory system, such a framework could be used to analyze the auditory processes contributing to and limiting speech ...

Spectro-temporal modulation transfer functions and speech intelligibility.

Detection thresholds for spectral and temporal modulations are measured using broadband spectra with sinusoidally rippled profiles that drift up or down the log-frequency axis at constant velocities. Spectro-temporal modulation transfer functions (MTFs) are derived as a function of ripple peak density (omega cycles/octave) and drifting velocity (omega Hz). The MTFs exhibit a low-pass function w...

Objective Audio Quality Assessment Based on Spectro-Temporal Modulation Analysis

Objective audio quality assessment is an interdisciplinary research area that incorporates audiology and machine learning. Although much work has been made on the machine learning aspect, the audiology aspect also deserves investigation. This thesis proposes a non-intrusive audio quality assessment algorithm, which is based on an auditory model that simulates human auditory system. The auditory...
