On the application of reverberation suppression to robust speech recognition

2012 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2012
In this paper, we study the effect of the design parameters of a single-channel reverberation suppression algorithm on reverberation-robust speech recognition. At the same time, reverberation compensation at the speech recognizer is investigated.

Underwater reverberation suppression based on non-negative matrix factorisation

Journal of Sound and Vibration, 2021
Reverberation is the main background interference in underwater active sonar target detection that seriously interferes with the extraction of the target highlight echo. In consideration of the difference in the time-frequency distributions of the target

A Reverberation Noise Suppression Method of Sonar Image Based on Shearlet Transform

IEEE Sensors Journal, 2023
A sonar image affected by reverberation noise would generate serious speckle noise in the image, which causes great trouble for the later sonar image target segmentation and detection. Therefore, noise suppression is a crucial preprocessing technique for

Adaptive Comb Waveform Design for Reverberation Suppression

OCEANS 2022, Hampton Roads, 2022
Comb waveforms possess the ability to strongly sup-press reverberation over a controllable range of Doppler shifts. This ability is measured by the Q-function, the Doppler marginal of the waveform’s Ambiguity Function (AF).
