We compare this feature with traditional accent- prediction features (based on part of speech and N-grams) as well as with several linguistically mo- tivated and manually labeled information structure features, such as whether a word is given, new, or contrastive. Our results show that the linguistic fea- tures do not lead to significant improvements, while accent ratio alone can yield prediction performance almost as good as the combination of any other sub- set of features. Moreover, this feature is ...
