Music selection interface for car audio system using SOM with personal distance function
EURASIP Journal on Audio, Speech, and Music Processing - Tập 2013 - Trang 1-15 - 2013
Devices such as smart phones and tablet PCs of various sizes have become increasingly popular, finding new applications, including in-car audio systems. This paper proposes a new car audio system. In the architecture, music data is stored in an online database, which users are then able to select a genre of music or a playlist from through a 2D interface. Self-organizing map, depending on a person...... hiện toàn bộ
Robust dialogue act detection based on partial sentence tree, derivation rule, and spectral clustering algorithm
EURASIP Journal on Audio, Speech, and Music Processing - Tập 2012 - Trang 1-9 - 2012
A novel approach for robust dialogue act detection in a spoken dialogue system is proposed. Shallow representation named partial sentence trees are employed to represent automatic speech recognition outputs. Parsing results of partial sentences can be decomposed into derivation rules, which turn out to be salient features for dialogue act detection. Data-driven dialogue acts are learned via an uns...... hiện toàn bộ
Spherical harmonic covariance and magnitude function encodings for beamformer design
EURASIP Journal on Audio, Speech, and Music Processing - Tập 2021 - Trang 1-17 - 2021
Microphone and speaker array designs have increasingly diverged from simple topologies due to diversity of physical host geometries and use cases. Effective beamformer design must now account for variation in the array’s acoustic radiation pattern, spatial distribution of target and noise sources, and intended beampattern directivity. Relevant tasks such as representing complex pressure fields, sp...... hiện toàn bộ
Whisper-based spoken term detection systems for search on speech ALBAYZIN evaluation challenge
EURASIP Journal on Audio, Speech, and Music Processing - - 2024
The vast amount of information stored in audio repositories makes necessary the development of efficient and automatic methods to search on audio content. In that direction, search on speech (SoS) has received much attention in the last decades. To motivate the development of automatic systems, ALBAYZIN evaluations include a search on speech challenge since 2012. This challenge releases several da...... hiện toàn bộ
Efficient Multichannel NLMS Implementation for Acoustic Echo Cancellation
EURASIP Journal on Audio, Speech, and Music Processing - Tập 2007 - Trang 1-6 - 2007
An acoustic echo cancellation structure with a single loudspeaker and multiple microphones is, from a system identification perspective, generally modelled as a single-input multiple-output system. Such a system thus implies specific echo-path models (adaptive filter) for every loudspeaker to microphone path. Due to the often large dimensionality of the filters, which is required to model rooms wi...... hiện toàn bộ
Multiple Source Localization Based on Acoustic Map De-Emphasis

Dual input neural networks for positional sound source localization
EURASIP Journal on Audio, Speech, and Music Processing - Tập 2023 - Trang 1-12 - 2023
In many signal processing applications, metadata may be advantageously used in conjunction with a high dimensional signal to produce a desired output. In the case of classical Sound Source Localization (SSL) algorithms, information from a high dimensional, multichannel audio signals received by many distributed microphones is combined with information describing acoustic properties of the scene, s...... hiện toàn bộ
Audio segmentation-by-classification approach based on factor analysis in broadcast news domain
EURASIP Journal on Audio, Speech, and Music Processing - Tập 2014 - Trang 1-13 - 2014
This paper studies a novel audio segmentation-by-classification approach based on factor analysis. The proposed technique compensates the within-class variability by using class-dependent factor loading matrices and obtains the scores by computing the log-likelihood ratio for the class model to a non-class model over fixed-length windows. Afterwards, these scores are smoothed to yield longer conti...... hiện toàn bộ

AUC optimization for deep learning-based voice activity detection
EURASIP Journal on Audio, Speech, and Music Processing - Tập 2022 - Trang 1-12 - 2022
Voice activity detection (VAD) based on deep neural networks (DNN) have demonstrated good performance in adverse acoustic environments. Current DNN-based VAD optimizes a surrogate function, e.g., minimum cross-entropy or minimum squared error, at a given decision threshold. However, VAD usually works on-the-fly with a dynamic decision threshold, and the receiver operating characteristic (ROC) curv...... hiện toàn bộ
