Age: See for yourself. Appearance: I really do not have time for that. Hi, is everything okay? Oh sure. I have a stack of work to do, my boss is on my back for no reason, one of the kids has been sent home sick from school and now I have to have a stupid conversation with you. But, yes, everything is wonderful. Thanks for the question. Are you sure? You sound quite anxious. What gave you this idea? The sound of your voice. What me? No, I always speak with such speed and intensity that strangers obviously backfire. This is just my personality. You can not fool me. My God, you sound just like the researchers at the University of Saarland in southwest Germany. Honestly, this is the first time someone has told me that. They just did a study on how stress affects our voices and found that a stressful day changes the way we talk. Obviously, after a hard day our breathing becomes faster, which makes us speak faster, louder and more intensely. This seems obvious. Well, that’s no matter how stressful we feel. We may feel completely calm and peaceful after a hard day, but changes in our voice will give the game. For example, you will never know that I am anxious. I will. No, you would not. How? Well, you almost cry, for a start. After all, whether you feel stressed or not, external stressors tend to activate your sympathetic nervous system, leading to the production of cortisol and adrenaline. And this is what makes your breathing faster, changing your voice. Chatterboxes. Either way, this study is excellent, because if voice tracking software can detect these changes, it can help doctors and employers diagnose stress before it becomes a problem. Not that it’s a problem for me. Your hair literally falls out of your head in real time. I can not help it! But wouldn’t it be wonderful? Stress is a universal cause of health problems, so early diagnosis has the potential to help millions of lives. Millions of people who are not me, obviously, because I’m completely fine. Why does your skin become pale? I do not know! Stop asking me so many questions! Wow, it’s very hot in here, isn’t it? Not really. Okay, okay, maybe I’m a little nervous. What gave it? The imperceptible bronchodilation of my airways? That. You are also bent over in the fetal position. There may be something in this study, you know. Say, “Stress can make your voice change.” Do not say: “YES, I ALREADY KNEW THAT! JESUS CHRIST!”
