Near-End Speech Enhancement
Since this auditory model takes into account short- time information, transients will receive more amplification than stationary vowels, which has been shown to be beneficial for intelligibility of speech in noise.
The proposed method is compared to unprocessed speech and two reference methods using an intelligibility listening test. Results show that the proposed method leads to significant intelligibility gains while still preserving quality.
The attached file contains Matlab code that implements the algorithm.
