Abstract

The bachelor thesis deals with the realization of experimental simulation biometric system enabling calculation of acoustic signal characteristics and recognition of its content. The theoretical part is focused on the characteristics of biometrics and biometric systems for user security identification and verification based on his voice and description of algorithms for analysis of acoustic signal. The practical part of the thesis is elaborated in the MATLAB programming language and is focused on complex quantitative analysis of acoustic signal in time, frequency and time frequency domain. In conclusion, based on the results of the work, it is evaluated which methods and parameters have the greatest potential to identify the correct speaker password in a simulated biometric system.
