PerMix: Anomalous sound detection by predicting the perturbation ratio of mixed samples
Jihoon Choi, Jung-Woo Choi
In anomalous sound detection based on self-supervised learning, the performance of the detection model largely depends on the selection of the pretext task through which the charac…
DeFTAN-II: Efficient Multichannel Speech Enhancement with Subgroup Processing
Dongheon Lee, Jung-Woo Choi
In this work, we present DeFTAN-II, an efficient multichannel speech enhancement model based on transformer architecture and subgroup processing. Despite the success of transformer…
Divided spectro-temporal attention for sound event localization and detection in real scenes for DCASE2023 challenge
Yusun Shul, Byeong-Yun Ko, Jung-Woo Choi
Localizing sounds and detecting events in different room environments is a difficult task, mainly due to the wide range of reflections and reverberations. When training neural netw…
DeFT-AN: Dense Frequency-Time Attentive Network for Multichannel Speech Enhancement
Dongheon Lee, Jung-Woo Choi
In this study, we propose a dense frequency-time attentive network (DeFT-AN) for multichannel speech enhancement. DeFT-AN is a mask estimation network that predicts a complex spect…
Inter-channel Conv-TasNet for multichannel speech enhancement
Dongheon Lee, Seongrae Kim, Jung-Woo Choi
Speech enhancement in multichannel settings has been realized by utilizing the spatial information embedded in multiple microphone signals. Moreover, deep neural networks (DNNs) ha…
Robust Sound Source Localization considering Similarity of Back-Propagation Signals
Inkyu An, Doheon Lee, Byeongho Jo +2
We present a novel, robust sound source localization algorithm considering back-propagation signals. Sound propagation paths are estimated by generating direct and reflection acous…
Diffraction-Aware Sound Localization for a Non-Line-of-Sight Source
Inkyu An, Doheon Lee, Jung-woo Choi +2
We present a novel sound localization algorithm for a non-line-of-sight (NLOS) sound source in indoor environments. Our approach exploits the diffraction properties of sound waves…
