The research activities are concentrated on some domains of the artificial neural network applications, especially on the applications of speech processing. The interest is concerned on some questions relate to speech synthesis. It is effort about the increase of its naturalness by the modelling of the prosodic parameters of the Czech language for the text-to-speech (TTS) synthesis, reduction of data extracted from the text and natural speech signal, which are necessary for neural network training (by the methods aim on the extraction of parameters and on the knowledge obtaining from the experimental data).

New research field is a speech signal processing for medical purposes. It means the speech analysis for children suffering of some neurological diseases (developmental dysphasia, epilepsy, autism etc). As a part of this research the databases are created for training and testung of neural nets. Apart of ill children sentences the healthy children (4 to 10 years age) sentences are recorded and processed (as a comparative database). It is part of joint research program with the Clinic of Paediatrie Neurology, Faculty of Medicine, Charles University in Prague. Master degree and Phd students from the Laboratory of Artificial Neural Network Applications (LANNA ) participate in both research areas.
