SPEECH ENHANCEMENT FOR FORENSIC PURPOSES

The research community interest in forensic audio processing has increased exponentially in the latest years, mostly as an effect of media coverage of cases where the debates in the courts of law have benefitted from forensic speech recording analyses. The enhancement of speech signals quality for forensic purposes targets the recordings that are difficult to understand and use in legal contexts, whereas speech telecommunications or artistic performance have different performance criteria. In this work, the forensic speech enhancement domain is discussed, together with an enhancement method we propose for forensic applications.
