| Abstract: | Forensic audio does not seldom consist of long recordings of multiple speakers engaged in a dialogue. An important task for forensic phoneticians is then to say (a) how many speakers are present in the recording and (b) who speaks when. This can also lead to the identification of audio segments that are relevant for detailed inspection. Speaker diarization provides the fundamental ability to automatically split audio streams into segments assigned to speakers (Tranter, 2003). Since current diarization systems do not require audio profiles of speakers and do not assume any given number of speakers, they support a wide range of applications. In this paper, we present our approach to leverages speaker diarization to support forensic audio analysis. This also implies the identification of challenges for diarization systems in this context and the necessity of a novel evaluation metric. |
