Journal Article
Representing Musical Instrument Sounds for Their Automatic Classification
Bozena Kostek,Andrzej Czyzewski +1 more
TL;DR: A study of the automatic classification of musical instrument sounds is presented allowing a discussion of the efficiency of the feature extraction process and its limitations.
Journal ArticleDOI
An audio-visual corpus for multimodal automatic speech recognition
TL;DR: Results achieved with the developed audio-visual automatic speech recognition (ASR) engine trained and tested with the material contained in the corpus are presented and discussed together with comparative test results employing a state-of-the-art/commercial ASR engine.
Journal ArticleDOI
Intelligent Processing of Stuttered Speech
TL;DR: The paper presents several methods of analyzing stuttered speech and describes attempts to establish those parameters that represent stuttering event and reports results of some experiments on automatic detection of speech disorder events that were based on both rough sets and artificial neural networks.
Journal ArticleDOI
Detection and localization of selected acoustic events in acoustic field for smart surveillance applications
TL;DR: A method for automatic determination of position of chosen sound events such as speech signals and impulse sounds in 3-dimensional space is presented, and the spatial filtration can be performed to separate sounds arriving from a chosen direction.
Journal ArticleDOI
Detection, classification and localization of acoustic events in the presence of background noise for acoustic surveillance of hazardous situations
TL;DR: It is found that the engineered algorithms provide a sufficient robustness in moderately intense noise in order to be applied to practical audio-visual surveillance systems.
