An Improved Array Steering Vector Estimation Method and Its Application in Speech Enhancement

open access: yesEURASIP Journal on Advances in Signal Processing, 2005
We propose a robust microphone array for speech enhancement and noise suppression. To overcome target signal cancellation problem of conventional beamformes caused by array imperfections or reverberation effects, the proposed method adopts arbitrary ...

Evaluation of single-channel reverberation suppression as preprocessing for acoustic event detection

open access: yes, 2022
S.1517-1520Acoustic event detection (AED) is increasingly present in applications such as health monitoring, security or home automation. A high accuracy is needed in the applications of AED to real-world scenarios.

Movement Disorders in Aicardi–Goutières Syndrome and Response to Immunomodulation

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT This study characterizes movement disorders and treatment responses in seven children with Aicardi–Goutières syndrome (AGS). We retrospectively evaluated motor phenotypes, neuroimaging, and interferon signatures in patients treated with baricitinib or anifrolumab. Spasticity affected all patients, while dystonia was present in 4/7.

Inverse Filtering and Principal Component Analysis Techniques for Speech Dereverberation

open access: yesAdvances in Electrical and Electronic Engineering, 2016
In this work, we present a single channel approach for early and late reverberation suppression. This approach can be decomposed into two stages. The first stage employs the inverse filter to augment the signal-to-reverberant energy ratio.

A blind speech enhancement algorithm for the suppression of late reverberation and noise [PDF]

open access: yes2009 IEEE International Conference on Acoustics, Speech and Signal Processing, 2009
This paper proposes a new speech enhancement algorithm for the suppression of background noise and late reverberation without a priori knowledge. A generalized spectral weighting rule based on estimations for the spectral variances of the late reverberant speech and background noise is used for speech enhancement.

Deep Subband Network for Joint Suppression of Echo, Noise and Reverberation in Real-Time Fullband Speech Communication

open access: yesIEEE International Conference on Acoustics, Speech, and Signal Processing, 2023
This paper presents a deep and lightweight subband neural network which jointly suppresses the common interference in real-time fullband speech communication: echo, noise and reverberation.

Modeling late reverberation in acoustic echo suppression

open access: yes, 2022
The traditional approach to cope with acoustic echoes is the use of an acoustic echo canceler (AEC). Usually, subband acoustic echo suppression (AES) is used after the AEC to suppress residual echoes which have not been subtracted.

Association Between Motor Pathway Damage and Motor Deficit in Upper and Lower Limb in People With MS

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Corticospinal tract damage is common in people with MS, but the degree of clinical symptoms varies. We hypothesize that corticospinal tract lesions are more extensive and severe in people with MS with motor impairments in both upper and lower limbs.

Noise-Canceling Office Chair with Multiple Reference Microphones

open access: yesApplied Sciences, 2018
Office employees are exposed to acoustic noise, especially in an open office environment. Passive or active headsets sufficiently reduce the level of noise, but their long-time wear is uncomfortable.

Lightweight Model for Fish Recognition Based on YOLOV5-MobilenetV3 and Sonar Images

open access: yesGuangdong nongye kexue, 2023
【Objective】Cage biometrics and statistics are one of the key reference factors for marine pasture farming management. Aiming at the interference of reverberation noise and complex background, this paper constructs fish detection data sets under different
