+## Augmented Data on R2R
+
+If you only want to use our data augmentation on the R2R dataset but don't need our models, you can directly download our augmented data on R2R (JSON file containing synthetic data generated by our speaker model) [here](http:https://people.eecs.berkeley.edu/~ronghang/projects/speaker_follower/data_augmentation/R2R_literal_speaker_data_augmentation_paths.json). This JSON file is in the same format as the original R2R dataset, with one synthetic instruction per sampled new trajectory.
+
+*Note that we first train on the combination of the original + augmented data, and then fine-tuned on the original training data.*
