We present a system for automated pho- netic clustering analysis of cognitive tests of phonemic verbal fluency, on which one must name words starting with a specific letter (e.g., ?F?) for one minute. Test re- sponses are typically subjected to man- ual phonetic clustering analysis that is labor-intensive and subject to inter-rater variability. Our system provides an au- tomated alternative. In a pilot study, we applied this system to tests of 55 novice and experienced professional fight- ers (boxers and mixed martial artists) and found that experienced fighters produced significantly longer chains of phonetically similar words, while no differences were found in the total number of words pro- duced. These findings are preliminary, but strongly suggest that our system can be used to detect...
