Mean Absolute Difference of Hierarchical ED: differences between the predicted and the ground-truth hierarchical ED values. The column Longer “Longer Segments” denotes the longer segments used to predict shorter segments; “GT” indicates that ground-truth values were employed. For example, under the “GT” condition, we used the ground-truth utterance-level ED to predict the word-level ED, whereas under the “Predicted” condition, we utilized the predicted utterance-level ED
