Fatigue Classification Using Chalder Fatigue Scale Based Vocal Biomarkers, VGGish Deep Representations, Prosodic Features and Meta Model Fusion
Voice is a compelling, non-invasive biomarker for fatigue, yet much of the field's reported success rests on evaluation protocols that quietly permit information leakage and collapse once that leakage is removed. This paper reframes the question, asking not how high accuracy can be pushed but how much fatigue signal th...
