Abstract

One of the main elements of the research in acoustics of crime is to compare the evidential recording with the comparative adequate pattern. Unfortunately, the evidential recording usually has poor quality and contains relatively high level of noise, which results from the way of its acquiring, namely eavesdropping or record of automatic monitoring. The signal quality and the noise to signal ratio have an impact on the value of the extracted voice metrics. In this paper we analyze factors that may have an impact on formants value in the human voice. Based on Six Sigma methodology we also designed and performed an experiment that allowed us to determine the extent in which various factors influence on the resulting parameters.
