Abstract

In this paper, we describe the use of Artificial Neural Network (ANN) to compute the acoustic features in analysing forensic speaker verification. In the computation, there are two datasets derived from speech recording of a simulated human trafficking crime, namely Forensic Evidence Data (FED) and Comparative Evidence Data (CED). In both datasets, sound segmentation is performed and then the acoustic features (Formant Frequencies F1, F2, F3, and F4) are extracted. The acoustic feature values are computed with ANN to predict an output with a targeted sound classification /a/, /i/ and /u/. The results are interpreted as forensic evidence against sound data in recorded evidence. With a result rate of more than 80%, this method might be studied more deeply to be developed and applied in evaluating recorded sound evidence for the legal case process.
