Method and system for processing subband signals using adaptive filters
TL;DR: In this paper, a method and system for processing subband signals using adaptive filters is provided. The system is implemented on an oversampled WOLA filterbank and includes an adaptive filter for each subband, and the functionality of improving the convergence properties of the adaptive filter.
Proceedings Article
An improved wavelet-based speech enhancement system.
TL;DR: Subjective and objective evaluations show that the proposed system improves the performance the wavelet thresholding algorithm.
Proceedings ArticleDOI
An integrated framework for multi-channel multi-source localization and voice activity detection
TL;DR: A spatial gradient steered response power using the phase transform (SRPPHAT) method which is capable of localization of competing speakers in overlapping conditions and an integrated framework of multi-source localization and voice activity detection is introduced.
Journal ArticleDOI
A hybrid subband adaptive system for speech enhancement in diffuse noise fields
TL;DR: A new hybrid system that integrates subband adaptive filters and a Wiener filter is proposed that is implemented on an oversampled DFT filterbank that efficiently integrates the SAF and theWiener filter components in the frequency-domain.

Etienne Cornu,Hamid Sheikhzadeh,Robert L. Brennan,Hamid Reza Abutalebi,E.C.Y. Tam,P. Iles,K.W. Wong +6 more
TL;DR: The low-resource VAD offers a performance comparable to that of the ETSI VAD in both clean and noisy conditions and uses less than 30% of the available system resources.
