Open the original- What it measures
- The authors report this drop across public models and commercial models alike. The study compares accent groups in conversational speech recorded between friends.
- What it does not show
- The abstract names three groups that performed worst. It does not give the size of each drop in the text; those values appear in a figure in the paper.
