Abstract: For the sake of preventing working air traffic controllers from getting themselves into a state of fatigue and (or) a state of stress,the characteristics of radiotelephony speech reaction of controllers in the two states were studied.Simulation control experiments were carried out to collect speech data on controllers in four states,sober,fatigue,stress and fatigue & stress.The reaction characteristics of controller were calculated.The characteristics of average reaction times for each flight,reaction time in overall process and different time segments were analyzed.The change features of the parameters affected by fatigue and stress were studied.The study showed that the average reaction times will increase under the influence of the two state,that fatigued controllers' reaction speed will slow,stability decrease and be worse because of longer working duration,and that under the influence of stress,the stability will decrease and the reaction speed will be slow after a spell.

Key words: air traffic controller, fatigue, stress, speech, characteristics of reaction
