A multi-channel speech enhancement method based on subband affine projection algorithm in combination with proposed circular nested microphone array
Dehghan Firoozabadi, Ali; Irarrazaval, Pablo; Adasme, Pablo; Durney, Hugo; Sanhueza, Miguel; Zabala-Blanco, David; Azurdia-Meza, Cesar A. (2020)In this paper, a novel multi-channel speech enhancement system is introduced based on a proposed circular nested microphone array (C-NMA) in combination with subband affine projection algorithm (SB-APA). The multi-channel ...

Evaluation of localization precision by proposed quasi-spherical nested microphone array in combination with multiresolution adaptive steered response power
Dehghan Firoozabadi, Ali; Irarrazaval, Pablo; Adasme, Pablo; Zabala-Blanco, David; Azurdia-Meza, Cesar A. (2020)Multiple sound source localization in noisy and reverberant conditions is one of the important challenges in the speech signal processing. The aim of this article is three-dimensional sound source localization in undesirable ...

Multiresolution speech enhancement based on proposed circular nested microphone array in combination with sub-band affine projection algorithm
Dehghan Firoozabadi, Ali; Irarrazaval, Pablo; Adasme, Pablo; Zabala-Blanco, David; Durney, Hugo; Sanhueza, Miguel; Palacios-Játiva, Pablo; Azurdia-Meza, Cesar A. (2020)Speech enhancement is one of the most important fields in audio and speech signal processing. The speech enhancement methods are divided into the single and multi-channel algorithms. The multi-channel methods increase the ...

Simultaneous sound source localization by proposed cuboids nested microphone array based on subband generalized eigenvalue decomposition
Dehghan Firoozabadi, Ali; Irarrazaval, Pablo; Adasme, Pablo; Durney, Hugo; Sanhueza, Miguel; Zabala-Blanco, David; Azurdia-Meza, Cesar A. (2020)Multiple sound source localization is an important application in speech processing. In this paper, a cuboids nested microphone array (CuNMA) is proposed for sound acquisition. Also, the spatial aliasing is eliminated by ...
