Abstract
Speaker change detection (SCD) is a preliminary step for many audio applications such as speaker segmentation and recognition. Thus, its robustness is crucial to achieve a good performance in the later steps. Especially, misses (false negatives) affect the results. For some applications, domain-specific characteristics can be used to improve the reliability of the SCD. In broadcast news and discussions, the cooccurrence of shot boundaries and change points provides a robust clue for speaker changes. In this paper, two multimodal approaches are presented that utilize the results of a shot boundary detection (SBD) step to improve the robustness of the SCD. Both approaches clearly outperform the audio-only approach and are exclusively applicable for TV broadcast news and plenary discussions.
