Speech Processing
 Vích, Robert
Proceedings of the Workshop on Speech Processing is a periodic publication collecting the contributions presented at the Czech-German Workshop organized every year in September in Prague This proceedings volume includes 22 papers by 41 authors. Papers are devoted to phonetics and prosody, construction of dialogs, speech analysis, synthesis, and recognition and voice conversion.

GLOTTAL SIGNAL MODIFICATION FOR EMOTIONAL SPEECH SYNTHESIS
 Vondra, Martin ; Vích, Robert
In the contribution speech decomposition into the source and vocal tract components is described. It is based on separation of the signal into the minimum- and maximum-phase speech components. Further the modification of the source speech component by changing the glottal model parameters is applied in order to achieve emotional speech by change of the neutral speech style

IMPROVING UNIT CONCATENATIONS IN EXPERIMENTAL SPEECH SYNTHESIS BASED UPON COMPLEX CEPSTRUM IN THE CONCATENATION-BASED TTS SYSTEM EPOS
 Staněk, Jan
During testing phase of a new speech analysis and synthesis methods based upon complex cepstrum and implemented in a TTS system Epos, we have discovered disturbing speech artifacts on the borders of the concatenated units. To eliminate these artifacts, we have chosen to practically implement and test usage of smoothing algorithms in the cepstral domain and observe its impact on the resulting synthesized speech. The results of our tests are presented in this paper.

Analysis of spectral changes in speech affected by orthodontic appliances
 Přibil, Jiří ; Přibilová, Anna
This paper is focused at investigation of influence of the upper removable plate and the lower fixed orthodontic brackets and their combination on spectral properties of produced speech. Spectral changes were analyzed and evaluated by spectrograms and mean Welch’s periodograms. From obtained results follows that the removable orthodontic appliance mainly affects spectrograms of speech, and these changes are most significant in voiced parts of spectrograms – corresponding to vowels, voiced consonants etc.
