dc.description.abstract | Forensic practitioners are faced more and more with large volumes of data. Therefore, there is a growing need for computational techniques to aid in evidence collection and analysis. With this study, we introduce a technique for preliminary analysis of audio evidence to discriminate between speech and non-speech. The novelty of our approach lies in the use of well-established speech quality measures for characterizing speech signals. These measures rely on models of human perception of speech to provide objective and reliable measurements of changes in characteristics that influence speech quality. We utilize this capability to compute quality scores between an audio and its noise-suppressed version and to model variations of these scores in speech as compared to those in non-speech audio. Tests performed on 11 datasets with widely varying characteristics show that the technique has a high discrimination capability, achieving an identification accuracy of 96 to 99% in most test cases, and offers good generalization properties across different datasets. Results also reveal that the technique is robust against encoding at low bit-rates, application of audio effects and degradations due to varying degrees of background noise. Performance comparisons made with existing studies show that the proposed method improves the state-of-the-art in audio content identification. (C) 2014 Elsevier B.V. All rights reserved. | en_US |
