CHARACTERIZING PERFORMANCE OF SPEAKER DIARIZATION SYSTEMS ON FAR-FIELD SPEECH USING STANDARD METHODS

摘要

To date, the bulk of research on speaker diarization has been conducted on telephone or near-field speech. As the need for technologies capable of handling conversational speech increases, it is necessary to establish the performance of state-of-the-art systems in this domain. In this work we evaluate the performance of an ivector/PLDA-based diarization system on the AMI Meeting Corpus, comparing performance on near-field, far-field, and signal-enhanced conditions.
