Abstract

Mobile phone identification from recorded speech signals is an audio forensic task that aims to establish the authenticity of a speech recording. The typical methodology to address this problem is to extract features from the entire signal, model the distribution of the features of each phone, and then perform classification on the testing data. Here, we demonstrate that extracting features from non-speech segments or extracting features from the entire recording and modeling them using a Universal Background Model (UBM) of speech improves classification accuracy. The paper’s contribution is in the disclosure of experimental results on two benchmark datasets, the MOBIPHONE and the CCNU Mobile datasets, demonstrating that non-speech features and UBM modeling yield higher classification accuracy even under noisy recording conditions and amplified speaker variability.
