Two-Microphone Dereverberation for Automatic Speech Recognition of Polish

open access: yesArchives of Acoustics, 2014
Reverberation is a common problem for many speech technologies, such as automatic speech recognition (ASR) systems. This paper investigates the novel combination of precedence, binaural and statistical independence cues for enhancing reverberant speech ...

Densely Connected Networks with Multiple Features for Classifying Sound Signals with Reverberation

open access: yesSensors, 2023
In indoor environments, reverberation can distort the signalseceived by active noise cancelation devices, posing a challenge to sound classification. Therefore, we combined three speech spectral features based on different frequency scales into a densely

Linear Frequency Modulated Reverberation Suppression Using Non-Negative Matrix Factorization Methods, Dechirping Transformation and Modulo Operation

open access: yesIEEE Access, 2020
In this study, we propose a reverberation suppression algorithm for linear frequency-modulated (LFM) pulse sonar systems using a non-negative matrix factorization (NMF) method.

Classroom acoustics and hearing ability as determinants for perceived social climate and intentions to stay at work

open access: yesNoise and Health, 2013
Background noise and room acoustics may impede social interactions by interfering with oral communication and other cognitive processes. Accordingly, recent research in school environments has showed that social relationships with peers and teachers are ...

Blind Estimation of Speech Transmission Index and Room Acoustic Parameters by Using Extended Model of Room Impulse Response Derived From Speech Signals

open access: yesIEEE Access, 2023
The speech transmission index (STI) and room acoustic parameters (RAPs) are essential metrics for assessing speech quality and predicting listening difficulty in a sound field.

The effect of room acoustics on the sleep quality of healthy sleepers

open access: yesNoise and Health, 2016
Introduction: Noise is one of the factors that can seriously disturb sleep, and sound volume is an important factor in this context. One strategy involves avoiding exposure to sounds in the night, while entail the minimization of background noise in a ...

Fast processing models effects of reflections on binaural unmasking

open access: yesActa Acustica, 2023
Sound reflections and late reverberation alter energetic and binaural cues of a target source, thereby affecting its detection in noise. Two experiments investigated detection of harmonic complex tones, centered around 500 Hz, in noise, in a virtual room

Reverberation suppression algorithm for LS beamforming based on Wiener post-filter

open access: yesDianzi Jishu Yingyong, 2018
Reverberation causes speech signal time and frequency to blur, and speech is difficult to understand when serious. In order to improve the speech quality, this paper presents a least squares beamforming reverberation suppression algorithm with Wiener ...

Augmenting Environmental Interaction in Audio Feedback Systems

open access: yesApplied Sciences, 2016
Audio feedback is defined as a positive feedback of acoustic signals where an audio input and output form a loop, and may be utilized artistically. This article presents new context-based controls over audio feedback, leading to the generation of desired
