SpeechCommandsV2-C (SC2-C) serves as a benchmark for DHAuDS in the context of test-time adaptation for audio classification. SC2-C, a subset of SpeechCommands V2, utilizes only test-set samples to address domain shift. Each sample in SC2-C has a duration of 1 second, a sample rate of 16 kHz, and belongs to one of 35 classes. The dataset comprises two sets: adaptation and evaluation sets. Each set comprises seven corruption categories and two levels. Seven corruption categories are defined: WHN, ENQ, END1, END2, ENSC, TST, and PSH. Two levels are defined: L1 and L2, where L2 indicates a higher degree of complexity. As for the evaluation and adaptation sets, each comprises 154,070 samples. In total, SC2-C consists of 308,140 samples, with each category-level, such as WHN-L1 or WHN-L2, containing 11,005 samples.
