Pseudokepstrogram a jeho použití při analýze řeči
Vích, Robert ; Vondra, Martin
Generalized cepstral speech analysis is briefly summarized and applied to the construction of cepstrograms. By means of cepstrograms and pseudo cepstrograms of clean and noise corrupted speech it is shown that pseudo cepstrograms are more robust to background noise. The mel-scale representation of the speech spectrum is further used as a pre-processing step in pseudo cepstrum visualization. This combination of nonlinear approaches proved to be a very effective tool in speech processing.
Hodnocení změny hlasu v TTS systému s kepstrálním popisem
Přibil, Jiří ; Přibilová, Anna
Voice conversion, i.e. modification of a speech signal to sound as if spoken by a different speaker, finds its use in speech synthesis with a new voice without necessity of a new database. It is very useful in special aids for blind and partially sighted people, e.g. Braille notetaker based on the Pocket PC. This paper evaluates voice conversion implemented in the Czech and Slovak text-to-speech (TTS) system based on cepstral description of speech database using the source-filter speech model.
Analýza procesů elektromagnetické emise v živých buňkách pomocí grafů signálových toků
Šrobár, Fedor
Living cells contain polar macromolecules and higher aggregates such as microtubules. These perform mechanic vibrations and emit electromagnetic radiation. Fröhlich proposed kinetic equations for occupancy numbers of vibration modes. Signal flow graphs are employed to represent causal relationships in the model. Analytical apparatus associated with the diagrams affords quantitative characterization of the system’s behaviour. Results of numerical simulations are interpreted with regard to cell physiology.
