Introduction: Among the many cardiovascular diseases, heart failure is a growing problem amongst aging populations around the world, affecting up to one in ten patients over the age of 70. According to the guidelines of the European Society of Cardiology, for the management of heart failure with reduced ejection fraction, pharmacological treatment...
Background:
Cardiovascular disease remains the leading cause of death in the European Union and worldwide. Constant improvement in cardiac care is leading to an increased number of patients with heart failure, which is a challenging condition in terms of clinical management. Cardiac resynchronization therapy is becoming more popular because of its...
The automatic segmentation and parametrization based on the frequency analysis was used to compare with manually annotated phones. The phones boundaries were fixed in places of relatively large changes in the energy distribution between the frequency bands. Frequency parametrization and clustering enabled the division of phones into groups (cluster...
The most popular systems for automatic sign language recognition are based on vision. They are user-friendly, but very sensitive to changes in regard to recording conditions. This paper presents a description of the construction of a more robust system-an accelerometer glove-as well as its application in the recognition of sign language gestures. T...
This paper presents the creation of a Polish Sign Language corpus suitable for recognition research and automatic translation of sign language. The recording approach used and the captured data modalities are presented, as well as the description of the acquisition system implementation. The evaluation of the collected corpus is presented and compa...
A comparative analysis of multi-language speech samples is conducted using acoustic characteristics of phoneme realisations in spoken languages. Different approaches to investigation of phonemic diversity in the context of language evolution are compared and discussed. We introduced our approach (materials and methods) and presented preliminary res...
The paper presents the possibility of automatic speech processing in order to determine the acoustic similarity between phones. Subsequent processing steps of recorded speech signal result in phones’ segmentation, even without prior knowledge of their boundaries. The use of frequency signal parameterization and clustering algorithms facilitates a d...
The paper presents the concept of the embedded solution for voice biometric access system. The most important requirements for access control systems are presented, as well as the resulting design intent. The architecture of the system, its functionality and the methods used to verify the speakers is described along with a discussion of performance...

The results of investigation of the differences among the phonemes of 574 languages all over the world
are presented. We attempt to verify the hypothesis of African origin for all languages and gradual languages
diversification on other parts of the globe. The obtained results justify the languages classification by applying
the methods used in evolu...
A new approach to speech normalisation is presented. A method that finds the optimal coefficient for linear slope of the warping function is described. The affine normalisation functions are suggested. Their coefficients depend on expected values of frequency when speech spectra are used as a density of probabilities. The method was developed for c...
Aspects of applying databases in computational linguistics are presented. An example of a dictionary and an n-gram model of the AGH automatic speech recognition system is depicted as well. An advantage of Berkeley DB, comparing to SQLite in time efficiency aspect is shown on this case.
An automatic speech recognition system for Polish is demonstrated. A few layers of our system are different from popular approaches as a result of differences between Polish and English languages.
A dictionary of Polish implemented as a data base for automatic speech recognition is presented. The dictionary allows improvement of recognition by language modelling using statistics stored in the data base. The data currently kept in the database are presented as well.
