Pseudokepstrální analýza řeči
Vích, Robert
Real generalized cepstral analysis is introduced and applied to speech deconvolution and vocal tract modeling. Finite impulse response pseudo cepstral vocal tract models with linear and minimum phase are derived and applied to speech synthesis.

Realizace TTS jako systémového ovladače pro Microsoft Speech API
Přibilová, Anna ; Přibil, Jiří
The paper deals with implementation of voice modification in the Czech and Slovak text-to-speech /TTS/ system as Microsoft speech application programming interface /MS SAPI/ TTS engine based on diphone inventory. The original male voice database serves for creation of three derived databases with modification factors given by the average formant and pitch shift between male, female and childish voices. The source-filter model as well as the harmonic speech model, both with cepstral description, were used.

Inclusion of the Czech and Slovak TTS System to the MS SAPI 5 Standard
Přibil, Jiří
The report is aimed at analysis of structure and basic functions of the Microsoft SAPI 5 standard for Windows platform. A new developed TTS Engine called TTSKubec to be included in our Czech and Slovak TTS system is mainly described. Modifications of current version of the TTS system based on the diphone speech inventory working with the cepstral and the harmonic speech synthesis are also mentioned in the report.

Transformace hlasu v parametrické syntéze řeči
Vondra, Martin
In the paper a voice transformation algorithm using the composite cepstral speech synthesis model is presented. The voice transformation is based on fundamentals frequency and speech rate scaling and speech resampling. By this approach it is possible to achieve transformation male-female of female- child and vice versa.

Realizace TTS jako systémového ovladače pro Microsoft Speech API
Přibil, Jiří
The paper is aimed to the analysis of structure and function of the Microsoft Speech Application Interface /SAPI/. Realization of the TTS system as the SAPI Engine is mainly discussed. Study and use of was MS SAPI motivated by requirement of increased applicability of current Czech and Slovak TTS system first of all in telecommunication services. Necessary modifications of our TTS system for impelementation into the SAPI standard are also mentioned.
