Speech Enhancement
Dr. David Eddins and Dr. Chang Liu (University of Texas) have a long-standing collaboration that includes speech enhancement based on amplification in the spectro-temporal modulation domain. Their work is on-going and slow-going but has illustrated that when the target source and interfering source(s) can be separated, spectro-temporal enhancement in a critical range around 2.0 cycles/octave can lead to substantial improvement in speech detection, recognition, and intelligibility.
