Vocal fatigue induced by prolonged oral reading: Analysis and detection

? Vocal fatigue on speech was analyzed after 3 h of continuous reading. ? Fundamental frequency and voice intensity do not seem correlated with vocal fatigue. ? A multi-speaker Fatigue/Non-Fatigue classifier gives an UA rate of 68.2%. ? Vocal fatigue seems to have a specific effect on closures during phonation. ? Filtering phonetic segments can improve the detection of vocal fatigue.
