Možnosti modelování prozodie TTS systému Epos s použitím MBROLA rozhraní
 Horák, Petr ; Chaloupka, Zdeněk
This paper deals with prosody modelling possibilities of the Epos Text-To Speech (TTS) sytem. The aim is to build the TTS system with an absolute duration modelling of the separate sounds and the possibility of using MBROLA compatible Czech voices. The Epos is a very flexible language independent TTS system. It can be widely configured without the need of recompilation. The use of editable rules for every step during the synthesis makes it easy to monitor the progress of the synthesis and to apply changes.

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.
