A Free Synthetic Corpus for Speaker Diarization Research

摘要

A synthetic corpus of dialogs was constructed from the Libri-Speech corpus, and is made freely available for diarization research. It includes over 90 h of training data, and over 9 h each of development and test data. Both 2-person and 3-person dialogs, with and without overlap, are included. Timing information is provided in several formats, and includes not only speaker segmentations, but also phoneme segmentations. As such, it is a useful starting point for general, particularly early-stage, diarization system development.
