Authors present a few remarks that could be helpful for constructors of electrogustometers. Building the new equipment considering presented hints should facilitate the process of electrogustometrical examination both for doctor and patient. The remarks concern among other results scale, database construction, stimulating current regulation, end-point indication and shape of the electrode.

Electrogustometry is a simple and fast method of taste examination. The directcurrent monopolar stimulation was most frequently used until now. Aim of the study was to evaluate usefulness of the new method based on bipolar stimulation with impulse-current. Furtherrnore, the authors wanted to determnine taste thresholds using the equipment. 113 volunteers (53 women and 60 men) in the age of 17-50 were involved. The current-impulse electrogustometer with a bipolar electrode is useful for evaluating the taste thresholds, and is useful for precise and repeatable measurements. The range for thresholds measured on 2/3 of the anterior tongue depended on sex.

Artykuł ma na celu zaprezentowanie sposobów komputerowego przetwarzania obrazów i dźwięków wykorzystywanych w badaniach pacjentów po usunięciu krtani. Metody komputerowe mają na celu wizualizację widma głosu pacjentów, umożliwienie komputerowej analizy otrzymanych obrazów, wyselekcjonowanie najważniejszych cech sygnałów, zarchiwizowanie danych oraz analizę systematyczną otrzymanych wyników. Celem badań jest porównanie obiektywnych właściwości sygnałów z subiektywną oceną postępu pacjenta w rehabilitacji.

The paper shows the methods for processing speech signals and imaging power spectral density of speech. The methods were applied in medicine as a tool for improving the patients' rehabilitation after tracheotomy. The adaptive algorithms and transversal filters were implemented to estimate the transfer function of human speech modeling tract. The estimation methods were based on autoregressive model. The pilot study on speakers' images, especially movements of lips and jaw, and their correlation with speech frequency has been presented.
