Definition
Speaker Change Detection (SCD) is a technique used to pinpoint exact timestamps where one speaker stops talking and another begins. It serves as a preliminary step in diarization, helping to segment continuous audio into homogeneous segments belonging to the same speaker. Algorithms typically analyze spectral changes and voice activity to detect these transitions accurately.
