This paper describes the creation of five new telephony speech databases for Central and Eastern European languages within the SpeechDat(E) project. The 5 languages concerned are Czech, Polish, Slovak, Hungarian, and Russian. The databases follow SpeechDat-II specifications with some language specific adaptation. The present paper describes the differences(More)
According to predictive coding models of sensory processing, stimulus expectations have a profound effect on sensory cortical responses. This was supported by experimental results, showing that fMRI repetition suppression (fMRI RS) for face stimuli is strongly modulated by the probability of stimulus repetitions throughout the visual cortical processing(More)
In this paper acoustic processing and modelling of the supra-segmental characteristics of speech is addressed, with the aim of incorporating advanced syntactic and semantic level processing of spoken language for speech recognition/understanding tasks. The proposed modelling approach is very similar to the one used in standard speech recognition, where(More)
BABEL is a joint European project under the COPERNICUS scheme (Project #1304) comprising partners from five Eastern European countries and three Western ones. The project is producing a multi-language database of five of the most widelydiffering Eastern European languages. The collection and formatting of the data conforms to the protocols established by(More)
This paper describes a large scale experiment in which eight research institutions have tested their audio partitioning and labeling algorithms on the same data, a multi-lingual database of news broadcasts, using the same evaluation tools and protocols. The experiments have provide more insight in the cross-lingual robustness of the methods and they have(More)
In the frame of the INCO-Copernicus program of European Commission we have started to develop an audio-visual pronunciation teaching and training method and software system for hearing and speech-handicapped persons to help them to control their speech production. A teaching method is drawn up for progression from the individual sound preparation to(More)
Parkinson’s disease (PD) is one of the most common neurodegenerative disorders. PD is referred as idiopathic, that is, as having no known cause; its main symptoms are tremor, rigidity and general loss of muscle control. Research shows that speech may be a useful indicator for discriminating patients with PD from healthy controls. The paper describes our(More)
The human speech contains and reflects information about the emotional state of the speaker. The importance of research of emotions is increasing in telematics, information technologies and even in health services. The research of the mean acoustical parameters of the emotions is a very complicated task. The emotions are mainly characterized by(More)
In the Laboratory of Speech Acoustics ASR research has been prepared, in which we were searching for the possibility to contribute to the higher linguistic processing levels of ASR – at syntactic, and semantic level – by acoustical preprocessing of the supra-segmental (prosodic) features. The subject of our current article is a semantic level processing,(More)
