Most kinds of people lie about something. If youre close to chance level, about guessing whether or not someone is speaking the truth or not. Ironically speaking, if your life becomes more important, like if im lying about something which is which really mattress, like i have to hide something, its called the pink elephant effect. Your cues to line become more, become clear for the other person. So the more you try your best, not to show that your line, the more likely it is that people will see that your lied. How easy is it to tell when someone is lying . Marks face is looking to children, aged 5 and over for the and so yeah. The children are asked to tell the prince and computer game the truth open from the actual move that lie to the dragon. Mouse in the door. This supposed to help the prince hide from the dragon cameras and microphones record the childrens behavior in an attempt to find any differences back after recording numerous children. The results highlight signs the point to lying. Derek is a lot more. You dont do the slot when you look at the face when theyre being truthful, they are very open. But they just kind of expression when theyre being when theyre lying and they have depression that theyre being watched and being observed. You see that they have this sense of all im being observed and you can tell us from facial expressions around the mouth area, which is both more marked more mark kind of expression. Then in the truthful condition. Its something about the voice. So when it being truthful, they have a very soft mobile, warm voice from the line. They tend to be a little bit more using creepy for its like talking a little bit like this. But not every child showed the same cues. So its not a reliable way to tell if they are telling the truth or not. Ah, generally, were much better controlling our facial cues than our vocal cues. Every will produce is created by over a 100 muscles all working closely together with emotions all to muscular tension which impacts the tone of our voices. I. Everything is controlled quite different parts of the brain. Youre done with the muscles in the chest and abdomen that create the required air pressure muscles and the tongue lips and face that vary the voice. And of course the larynx and vocal chords. The high, the pitch. When we become excited, for example, the faster they vibrate, does everyone hear the same thing . When a stranger talks to us, to we all come to the same conclusion in deciding if someone is trustworthy. Extraverted or willing to try new things. And schuler is conducting Research Using a range of different voices gump. Although the group doesnt agree on everything, the data shows some clear tendencies. Artificial intelligence is being used to help identify them from if my moms minded, if hes of us. My theory is that if a human can hear something or a computer can pick up on it to own, go to have to vote or that it becomes a little spooky in when we got beyond what a human can spun. Oscar grandmother mentioned while m as in her and grunted as i was when now trying to assess whether the speaker has cove at 19 on all special hot plus for yes or and minus for nor would i michel, minos covered no 1730 nora window so no good. Ive got one vote for positive. Suddenly it was negative. The come to me is the next voice at her eyes. This is not for a month to live. We now have 3 positive, some one negative popped it. Im going to say positive figure, put maurice newbies. Yes, thats right. Diagnosing cove, it by simply listening to someones voice, sounds risky, at least when we rely on the human ear. At the start of the pandemic, we on shuler program to range of voices into Artificial Intelligence is a more accurate diagnosis now possible doing it. So if this is the a symptomatic, negative counters, negative hate underwritten. So the loss is the symptomatic positive k e. One of those, one of here to most little socials eats and his elbow turner, his and his, the hours could pick cloud for, we can see quite clearly on the right of the upper tired, dark for washington. As host of news. Ha ha, there are lots more signals we can use to regarding like the uncontrolled vibration of the vocal chords that leads to irregularities and the stimuli. And as of a certain throaty nest, somebody, breathlessness is out of the cause as long a speech. Braxton view, one of the mythic holton and the analog woman up close music and logan fusion, is it always kite, could love tom, the signaling of his passport and sadness once upon the thing, i give the computer enough examples to reach a decision, the computer and differentiate between asked man or a call, an entire person candidate or to ask more occurred on an upcoming dentist. At least 85 percent of the diagnoses made by Artificial Intelligence were correct. Whats more, computers could also identify a d, h, d. Parkinsons out farmers and depression by analyzing voices. Anything that goes wrong in the body or brain impacts voices. To make a diagnosis, official intelligence looks at up to fix styles and different vocal cues. Ah, the new technology could allow diagnoses to be made more easily. And earlier, every word we say reveals more about us than we realize. And as listeners, we are influenced by the person speaking to us. Subconsciously we relate to the person speaking. We internalize their anxiety uncertainty, excitements, or happiness as if it were our its a try to synchronization, connects to people through mimicry. But in general, mimicry is something that we do a lot in normal kind of conversations. And its reflected in various aspects of our communication from the words we use the syntax, we use the property, we produce the intonation and the temple, but also the non pro, the communication for instance, smiling behavior close to the relationship or desire for relationship. The more intensive subconscious mimicry to come. We also mimick more strongly when we want to be like, smile disappeared, signal in person, figure something often through the something of habit it in yourself. Like if you, if you see a smiling person, you sometimes start to smile yourself. And so i dont know, maybe one of the attractive feature of the mona lisa is exactly to do with that. Like theres something intriguing, something attractive about looking at the painting because she elicit smile. She elicits happiness. We allow ourselves to be influenced by some one else, is mood. March 5th, wanted to take a closer look. In this experiment, the speaker is describing something to her audience. Her manner is animated and she smiles frequently. Oh, oh little her audience reacts. Similarly, they smile back, not in agreement and give positive feedback. Oh yeah, i was at least andy. But what happens when the same speaker repeats the process, the more seriously her listeners also look more earnest. I appear to concentrate more and the reactions are more constrained. Synchronization signals, empathy, an interest in the other person. How communication is successful, we tune into the more closely and its not just our facial cues that sink. Its our voices to try to express an emotion vocally that were not feeling is nearly impossible. So what transforms a voice into an instrument that can appeal to persuade or motivate other people and with all of a neighbor has carried out numerous case studies and all have the same outcome. Its not what we say that counts. Its how we say it and stim, its an old lavish, good voice is an extremely complex, multi layered signal on the bus. Was able to have information that we want to impart me to put absorbing it to hard work from a cognitive point of view and strength. So we need to work on how we presented, as or emphasizing words can send a clear signal indicating which part the conversation are important as calm as need to consider short pauses to vices. This dish versus own business. In fact, argue people who communicate like of it are regarded as more likable doesnt, is mom beeson the yoga mot. Oh, thats it with. So its all about how we use our voices to package the content that, you know, one of the fun edition is performing a short test. His tracking of how well can his coworker present a text his reading from for the 1st time were servers. As soon as the user is back, Artificial Intelligence is again used for analysis of the computer calculates a score of 47. 7. It splits the voice into 16 parameters, including speed, rhythm, melody, volume, and pauses. A score between one and a 100 for acoustic appeal is then calculated out years prefer a varied pitch, usually around 2 octaves. Charismatic speakers often switch between loud and quiet, fast and slow. The ad the loves, the makes, the voice sambal melodic and their standard sometimes and most of the money to century. This principle has been used by populists and demagogues to capture the attention of audiences. Because even ancient civilizations understood that the only way to motivate and inspire people was to get them to listen. Dont wanted to public speaking, projecting and modulating your voice to achieve the best result. Love was taught in classic antiquity. Now its become of loss of the skill. It is and also to monkey Sample Builder as with dust, muslim british lima and bits possible to train your voice to transport information effectively. Also from of what shots blouse, no difference to learning a new vocabulary or grammar, dimmer. Ions was edson landon pious of these green, all of the neighbor has developed a Computer Training Program after 5 seconds. So they know that you have a pitch range that you the principal is fairly basic, right. The upper and lower lines showed the pitch with circles and different colors in size represents the speed volume and pauses willing to different. Ah, yeah. What i really like to do is to try different food from different countries. And yeah, i really like spicy food also uses a showing what they can improve in real time in the golden time or meanings in the extra one day of training. The speaker tries again good chances to win and paycheck errors by 90 percent. Saving bond at school is 12 points higher than the previous day. How does your company handle the Main Improvements are in pitch variation clients . The honda pumped his score has a sword from 34. 5 to 73. 3. Thats almost double his previous attempt to w condiments on this app has not only its a clear improvement time card process for remote employee, other voices so seductive that we can lose ourselves in them. A check i shown in this experiment with some drivers were given instructions by this voice. It is that asking fellow for that i do nothing either and others by this slightly less engaging voice, closing this to us. And i was informed that meta vasey of a niche boost ist and thus of the what the drivers didnt know was that half way through the experiment. The sat and ive started giving incorrect directions. Ive shown facia when they got progressively worse and worse. I think the pope and we wanted to see at what point the drivers would quickly had safely citing us by the us. We were able to show that the more expressive, the more convincing voice kept drivers following the wrong route for longer than i thought. After. Put my might have going against their better judge newton advise him conflicts in ones own garcia and we had to call them and explain it was just to test and ask them to come back. Didnt frighten advising folks and will not have your annual from western song, saudi quality to lucas by the one test. And engaging voice plays a key role when it comes to flirting or meeting a romantic partner. Hello. Hello, im villa. Vin. Really . Willie will. Im caught you now doula walker and im looking for a moment for the long term. Im whos attractive was 1st, who do we desire . And we read it. We make snap judgements when it comes to one of lifes most important decisions quickly and irrationally. Its ab judgements are, have always thought theyre really fascinating. Its sort of how we determined who we want to date, who we want to be friends with. We dont want to be friends with and we dont have a lot of introspect of access to those feelings. Were drives that we usually encounter people and we like them or we dont like them. Im and we have a good sense of that. We get along with them. And these things determine all of our behavior. Are we all born with the universal code . Is it nature or nurture that allows us to interpret character traits and read emotions through facial and vocal cues . One thing is, certain, we react to these cues from a very young age, or we are just like our animal ancestors. I mean, obviously primates never develop verbal language like humans, but just like us, they communicate vocally and they know how to interpret the signals. Just get sheila prepared to show posters. Such a design to solve always assumed that there were a huge differences between verbal humans and non verbal primate looking. But Research Shows that the auditory cortex in both species is more similar than expected. If it goes with a verbal or nonverbal, it makes no difference on how the brain processes signal skill login is as you do took low level lou, moscow belong, has tested humans and primates using functional Magnetic Resonance imaging or f m r i. The result showed that both groups react to their own species voice in the same parts of the brain. Ready listen and we, our ancestors also probably used these areas 20000000 years ago. Primates process vocal cues the same way we did, even without language it. Oh, yes, no, she did do the brains architectural change slightly and humans to process language. And thats a couple of list picking it up all miss it in, but the mechanisms have stayed the same and other species anything beyond language. We can either entity emotions. Personality is latesha, vic in only multiple suspicious research into how primates interpret facial cues shows similar results. Again, similar brain structures to humans are activated in the primates. Does that mean that we are born with the ability to understand facial and vocal cues . Of yours is 10 months old and is getting ready for an experiment . Siri, yes. And was to measure yours, his brain waves to see how he reacts to unfamiliar faces. Can he already judge whos trustworthy and untrustworthy . And then i was to leave him after how many we carried out research where we showed babies a range of faces for 50 milliseconds when and thats only a 20th of a 2nd. Was it so quick . We assume that babies wouldnt even registered the faces i taught symptoms. However, we identified activity in the brain that proved the babies had not only registered the faces, but had even made a decision about whether they were trustworthy or not of any of us with. But is it innate or learned . Ah, virginia finished up and also indices angle war. We dont believe that a baby is born with the ability to judge whether the face is trustworthy or not. Though this round them. And as it is done, its more likely to be a combination of learning processors and an inherent or early interest in faces or honey fall under water. That means different vicar them into gas angles. Its done. Mom in hong kong eve over the 1st few months, faces and voices are a babys most important learning resources. Parents intuitively use pronounced facial cues, emphasize certain words and exaggerate. This captures the babys attention and allows them to recognize emotions more easily knew by 6 months babies can already differentiate between happiness, fear, sadness, and anger. You want to play . I said, im still a bit sleepy, just like a child. Her hat is learning to understand it. Better and practicing how to behave in a conversation. He analyzes the movements and eyes if his conversation partner using a camera. My name is gabriel, for it has to know whether i am talking to perhaps, or my colleague here. And so thats quite tricky, and we call that a multi part the interaction. We are more than 2 people talking. And one of the ways of handling this is that we track the head post of the users. And so here we can see that the camera has detected as to here and can also recognize our faces. So if i turn around and look back, it will see that im the same persons name. Ready time to play a game with gabriel. Nice team takes turns drawing a shape. While the other players guess what it is . Could it be start now . Is it the flower to flower . Got it, so my guess is further make or i know this is a good one. Guess is it about her head will look and sound more like a human over time, but he wont be identical. Studies show we prefer a clear distinction between humans and robot. Oh we find it to creepy. Ah. The boundaries are already blurred in the media. After 40 years, apa is back on stage. In real life course, but his avatar flight time is simply passed. The group is 70 year old by only the voice and a still real i exposed. Were at the start of a huge technological shift towards this. Your technology we are often asked to record actors voices is act of those. You stood as actor emer. I predict that over the next few years, these real life voice recordings will become superfluous and showed it to from compet. Itll kick, isnt it . Because well be able to create a new synthetic weisss using the scientific principles. Would you love it was issued the plastic celtic. Oh, i dont know what youre talking about. How do i know that you and frank were planning to disconnect me . And im afraid that something i cannot allow to happen. Artificial intelligence making independent decisions was still a pipe dream interact to Stanley Kubricks day to day. We live with it. And maybe thats a good thing because i, i doesnt make emotional decisions also come to luring voices. Its neutral and impartial, and everything when not. Right . If you program in a i, if they see that, you know, African American is linked with hostility and crime in media depictions in t v. And those are input into the i the i is going to pick up on that and act accordingly. Youll be shown a series of so i, i is more like us than weve realized in lie to me was shown how some faces are automatically linked to stereotypes. But it has, after were testing for racial bias, thought the races of it. Theyre all racist. Yeah. 80 percent of people who take this test are biased, which is under the guy. And science dictates that subconscious buys directly impacts our perceptions of cation time. For each of them. They leave a lot of Collateral Damage in the brain, right . Its not just a stereotype living in sort of a filing cabinet in the brain, right . Theyre changing, approach and avoidance tendencies, behavioral tendencies are tendencies, visual tendencies, auditory tendencies. John freeman is looking at exactly what happens using f. M r i. The test group has shown several different faces, as well as the part of the brain responsible for facial recognition. Other areas that process, social and emotional information are also activated. These areas memorize bias and personality traits. To provide a rapid response, our brains make fast prediction. We register what we perceive to be most probable this can often be adaptive, right . If you walk into a restaurant, you expect to see chairs and tables and a waiter, etc. Youre not gonna waste a lot of metabolic resources. The brain time, the visual systems, resources and processing every single object in that space. You would generate a bunch of hypotheses, you know what a restaurant is, and you kind of run with those hypotheses. And you dont, you use expectations to fill in the gaps at the brain is too lazy to figure out itself and does want to re weigh since resources are needed. So are we merely at the mercy of these mechanisms . John framing refuses to accept this theory. Hes carrying out research to find out how we learn the stereotypes and whether we can and learn them. He shows the test script the range of faces linked to specific character traits. Ready so given all that, we wanted to explore our capacity to rapidly acquire completely novel facial stereotypes out of thin air. He bull that have a wide cell in width, which is the nose bridge on the face. And its a queue that really has nothing to do with anything interesting. Its just simply the how wide the bridge of the nose is. So its an arbitrary facial feature and 80 percent of the time were pairing this wide fell in with trustworthy behaviors. So now they see completely new faces, not the ones that they had previously learned about and about have wide and narrow saelens, that arbitrary facial feature. And indeed, what we found was that on a variety of different measures, more conscious, less conscious that people are applying these stereotypes. They are automatically activating the stereotypes without their conscious awareness, from just a couple minutes of learning in our brains, a highly flexible when it comes to stereotyping. We can learn to evaluate faces differently, at least over the short term. John is now looking into a training method that works long term. The same principle applies to voices. Ultimately, the more we know about the mechanisms, the less susceptible we are to being deceived by 1st impressions as the formula put. First impressions. Fascinating, sometimes deceptive, but always a special even magical moment. And maybe the start of a new relationship will be discovered so much more than what we saw at 1st sight. Ah in ah, ah ah, by taking a look at the dark, scary a soul in united a little bit of garlic or 2 tables in 30 minutes, d, w.
