+# EchoDialogue
+
+EchoDialogue is an emotional spoken-dialogue dataset with single-turn and
+multi-turn configurations. The single-turn split is being prepared as
+anonymous WebDataset shards.
+
+Each single-turn sample contains query audio, response audio, dialogue text,
+emotion annotations, speaking-style annotations, and reasoning metadata.
+Original UUIDs, storage paths, and source filenames are not published.
+
+The multi-turn configuration will be added separately.
