Abstract:
In this paper the possibilities of modern audio-processing systems have been described. One of the most important tasks is a proper definition of feature vectors. For example, the long-term spectra vector has been chosen as the background for text-independent verification system.<br>A system of audio processing has been designed and performed in CMOS technology. The prototype contains high precision CMOS integrated filters and also digital memory to control all functions of audio signal processing, including software radio capabilities. The implementation of the proposed algorithm as hardware-software system, including mixed analog-digital approach, should improve the speed and also the quality of the system.
