EN The speech signal emitted by humans may be a source of useful diagnostic and prognostic information. The signal may become, indirectly by some selected parameters, an additional source of information concerning the condition of the patient's vocal tract anatomy, as well as physiology and pathology ([...]

EN With the present development of digital registration and methods for processing speech it is possible to make effective objective acoustic diagnostics for medical purposes. These methods are useful as all pathologies and diseases of the human vocal tract influence the quality of a patient’s speech s[...]

EN The nature of speech signal is very complicated, that causes that its visualization and further analysis, without some initial pre-processing, is very complicated and doesn't always bring the desired effects. Speech signal in most cases is represented by videograms. The analysis of these forms of si[...]

EN Most diseases of the vocal tract cause changes in the voice quality. Acoustic analysis of the speech signal is a widely used, noninvasive, objective and low-cost method of laryngeal pathology recognition and classification. There have been numerous attempts [1-3] to develop an automatic system which[...]

PL Sygnał mowy posiada bardzo skomplikowaną naturę, która sprawia że jego zobrazowanie oraz dalsza analiza bez operacji wstępnego przetworzenia są trudne i nie zawsze przynoszą pożądane efekty. W wielu pracach sygnał mowy przedstawiany jest w postaci wideogramów, będących wykresami czasowo - częstotliw[...]

PL W pracy przedstawiono badania dotyczące metod przetwarzania sygnału akustycznego do oceny i klasyfikacji mowy po zabiegach w obrębie kanału głosowego. W zagadnieniach rozpoznawania mowy, problem dotyczy ujawniania semantycznych aspektów wypowiedzi. Natomiast w zagadnieniach diagnostyki medycznej prz[...]
EN In the work has been shown from studies concerning the application of modified acoustic signal processing methods to the task of evaluation and classification of larynx surgery effects. The goal of the standard speech recognition studies is to reveal the semantic aspects of the pronounced text. In t[...]
