This paper deals with the correlation between physical fatigue and speech signals. A treadmill task to increase fatigue anda set of subjective questionnaire for rating tiredness were designed. The results from the questionnaire and the collectedbio-signals showed that the designed task imposes physical fatigue. The t-test for two-related-samples between the speechsignals and fatigue showed that the parameters statistically significant to fatigue are fundamental frequency, first and secondformant frequencies, long term average spectral slope, smoothed pitch perturbation quotient, relative average perturbation,pitch perturbation quotient, cepstral peak prominence, and harmonics to noise ratio. According to the experimental results, itis shown that mouth is opened small and voice is changed to be breathy as the physical fatigue accumulates.
