Roll Change at Hannover Messe 2019: from conference participants to conference interpreter

Change of rolls within this week at Hannover Fair: first as participant I attend conference, sitting there among other participants, fully relaxed, having conversation with other participants; the other day I have the privilege of enjoying high performance sports, for the brain, though: sitting in the soundproof booth, I hear from the headset (“input”)  and process speeches in German and speak in almost real-time (actually with a fraction of a second or several seconds of input-output-lag /EVS)  into Chinese (“output”) into the microphone, which then are transmitted via infrared receivers to the headsets of conference participants; the name of this high performance sport:  simultaneous interpretation
