This paper looks at the effect of repeated replay on intelligibility: Hilkhuysen, G., Lloyd, J., Huckvale, M., "Effects of replay on the intelligibility of noisy speech", Proc. 46th AES Conference on Audio Forensics, Denver Colorado, 2012, pp50-56. A PDF is available at: It shows that while intelligibility reaches a plateau after 5 repeats, confidence in one's judgement continues to increase beyond 5 repeats.
