Overlapped Speech Detection

Definition
Overlapped Speech Detection (OSD) is a specialized task in speech processing that pinpoints intervals of concurrent vocalizations. Unlike speaker diarization which focuses on ‘who spoke when’, OSD specifically handles the complexity of overlapping voices, which often degrades automatic speech recognition performance. It utilizes acoustic features and temporal modeling to distinguish simultaneous speech events, enabling more robust transcription in noisy, multi-party conversations.
Summary
The process of identifying time segments where two or more speakers talk simultaneously in an audio stream.
