Speakers identification using ALIZE library
Skulínek, Zdeněk ; Burget, Radim (referee) ; Přinosil, Jiří (advisor)
Recently computing power has been significantly increasing and speaker identification systems have been drawing to the foreground among others. Many libraries have been developed, no matter if open--source or proprietary. One of them is for example ALIZE that was developed at Avignon university. This library offers general concept for staff with biometric values, statistic computations and complex framework for intended application. The goal of this thesis is to test this library, namely by constructing a practical application for speaker identification. This thesis describes successful assembly of that application. Application is platform independent and it is also tested on three basic platforms. These platforms are attached as files into VirtualBox virtual machine. This thesis takes notice of practical experiences with ALIZE library and also describes it's structure and architecture. There are 50 patterns of 9 speakers used for testing in average length 20 seconds. Application recognizes speakers very reliable in these given patterns. Therefore real neccesary length test for speaker recognition was accomplished at the end of this thesis.

Parallel implementation of Goertzel algorithm
Skulínek, Zdeněk ; Smékal, Zdeněk (referee) ; Sysel, Petr (advisor)
Technical problems make impossible steadily increase processor's clock frequency. Their power are currently growing due to increasing number of cores. It brings need for new approaches in programming such parallel systems. This thesis shows how to use paralelism in digital signal processing. As an example, it will be presented here implementation of the Geortzel's algorithm using the processing power of the graphics chip.
