+# ChainBench-ADD
+
+ChainBench-ADD is a **delivery-aware benchmark for audio deepfake detection**. It is designed to evaluate whether audio deepfake detectors remain reliable after realistic post-generation delivery effects such as compression, telephony degradation, replay-style simulation, and hybrid transformation chains.
+
+## Dataset Description
+
+### Dataset Summary
+
+ChainBench-ADD focuses on **post-generation delivery effects** in audio deepfake detection. Rather than evaluating only clean bona fide and clean spoofed speech, it organizes samples into controlled delivery conditions so that robustness can be studied under more realistic downstream transformations.
+
+The benchmark includes both bona fide and spoof speech, supports English and Mandarin Chinese, and provides metadata for structured evaluation across delivery conditions, operator chains, and protocol splits.
