i don't get the answer in the hallway by invisible river that flows through the sky starts march 23rd on d, w. ah no. hello. hello. hello lou, i look a word 1st impression and stress, shall i? we know i can trust her, but not him. she's lying. and so is he. but he seems reliable along the love of trustworthiness, how you perceive in another person's face, even when they're complete, strangers can predict criminal sentencing decisions, including up to capital punishment, and can predict hiring decisions, free flanks at someone's face. all the sound of their voice can affect our decisions. the bottle gathering information from facial and vocal cues has been fundamental to social interactions almost like which has only been around for tens of thousands of years. which in evolutionary terms, and it is no more than a blink of the eye. although yield. first impressions can be alluring, but often deceptive. i'm looking forward to tomorrow. i'll face and voice reveal a lot about us. out moved out disposition, i'll help a point to what's going on inside us in the queues that give can even be interpreted by artificial intelligence. english. this is in science fiction from longer of science fiction has been predicting this development for age is a government of it. it's still hard to fathom and at least feelings skeptical and uneasy because we're not used to live on top of her for hulu . ah, we encounter strangers every day, and you face an unfamiliar voice. a unique and distinct may express al individual ality, but they also help us decide whether we liked the person and whether we accept or reject their advances. ah, decisions we make instantly, ah, but just a 100 seconds of exposure. people already made up their mind about trustworthiness and competence and dominance, but they're making up their mind takes, you know, several hundreds of milliseconds, but you only need a very quick glance on their certain facial features. i'm even in a static photograph that convey ah, levels of intelligence, and that can lead to judgments and, and bias decisions. john freeman is looking at what happens in our brain after a short glance at someone's face. his theory. many of these instantaneous decisions are based on learned types in the same applies to voices. hospital law continues to find evidence that we associate certain emotions and traits with how someone's voice sounds. it will see there, we see voices as a type of auditory face. we need just one word to form an opinion such a voice like this in welcome to go, o is seen as inspiring and confident by most people. whereas this one leaves the listener, thinking they wouldn't trust him with their money. is that the hello hello. hello. and know, hi rule the science saying, do we all see the same thing when we look at someone's face? john freeman uses a special morphing program to get a more accurate hands. he can alter agenda, age mood and character traits softly. if you ask hundreds of different subjects to judge the trustworthiness of these individual faces, you'll find that they generally agree in terms of being highly correlated with one another. so the same faces appear trustworthy or relatively untrustworthy across the board. generally, although we're all different, the result is surprisingly similar for everyone. at least if i asked if someone is trustworthy. the 1st impression is when we decide who we want to communicate, cooperate or form a close relationship with me. is it surprising that people have these kinds of unconscious tendencies despite humans being such rational creatures? i would say not really, right? when we think evolutionarily about it in terms of our evolutionary pass, you know, before we had verbal language, right? as non human primates, i'm nonverbal communication and ah, using facial appearance, using a choose of the phase voice embody, were really critical, right? for survival, for the maintenance of resources, for building social group. it can be attributed to our evolution ah, making instant decisions about who his friend or foe greatly increased our chances of survival. as pack animals, we've always formed communities. long before language played a role, humans developed a keen sense of how those around them felt and being able to read the room is a huge advantage. if someone in the group is scared, your own life may also be in danger to if someone is seething with rage, you pluck hate them or run. ah, our brains are still wide the same way to day. as soon as we encounter someone new, we immediately attempt to establish whether they are with us or against us. 2 the what to what extent to these 1st impressions actually alter our behavior, that before the evidence shows that they have a strong impact, sophomore in the back to the force, it pulls up wizard. they predict all sorts of downstream social outcomes and real world consequences. and so, you know, when the findings like faces that appear more competent are more likely to be, i'm elected to senator and governor positions in the united states. and even presidential candidates are more likely to win in united states. compton, looking managers and attractive people, a paid more, and defendants who look untrustworthy. i given long sentences, but what about our voices? we can here find nuances of confidence, dominance, and competence to even if they have little in common with the speakers, actual personality. with beyond words of voice also transports emotions and can even bring things to life. hope it's become real because we relate to like other human beings. so used to put more oh city. it illustrates how we instinctively relate to a human personality. if it has a voice, so co appleton will only deliver on a puppet, for example. and because of changing body cues and changing voice, vocal cues that the perception of the emotion, the perception of, ah, the person's or the, the puppets intentions are changed. oh yes. let me in the i said just a little bit generous t sympathetic. i'm been hearing our brains create real people from the voices they hear. even when the people aren't real happy to configure the once you give a machine a voice, it gets a personality as if it were human machine consist of anyway, it's an automatic reflex as your auto magic. there will shasky mult good decal done in will, and research shows that people's feelings change if their computer, if your car or coffee machine has a voice in your who the company to said, well, the vocal acoustics we give machines, could even determine how we interact with them, it did tell me not to call them, and the old one is you might want the other clinician perhaps wake up, wake up. how can i help you? what can you do? you can, for example, ask me to introduce myself or to chat a little. can you introduce yourself? i'm a firm at robot, a social robot bill to interact with people in the same way you interact with each other. so i can smile and nod. gabriel's cancer is one of the creative dispersion process. the top of the robot was launched in 2011. i looked a bit more crude back then with cable sticking out from my head. they came up with the idea to cover the cables with a fur hat. and that ladies and gentlemen is where the main per head comes from. i don't really need my for head anymore. i look pretty as i am. don't you think? i don't know what the original interest comes from really? i think it's a very fascinating idea of creating and now an agent that interacts like a human and behaves like a human. it's fascinating by its own right. but it's also again back to the idea that if we can do that, we start to get the better understanding of how we as humans work in the future. gabriel's cancer wants for her to behave like a human during a conversation. but as soon as scientists try to transfer our human behavior to machines, it quickly becomes apparent how complex or behaviors are. but i'm originally do you like being on today for how it's supposed to make small talk? robot searches the way on his own, for responses. what did you, what do you mean by that? and you are quite stupid. free. ruth? is this a for so i have no idea what the robert would say next. so it's, it's, it's a surprise for me. what it says and it's a bit fascinating to see how the conversation on post ah, although the conversation takes some antics spec to turns her head has already mastered the basics when to speak. and where the conversation partner is looking and how much i contact is appropriate from the scientists to program. so with a whole range of emotional facial cues. however, the find a difference is we express using mimic and our voices are proving trickier. so as humans, for example, we have this micro expressions, so my eyes move a little bit all the time. i make small movements with my face, and we want the robot to have those small movements old. so otherwise it looks very robotic and not very human like. so we think that the face is extremely important and the way we give feedback to each other and everything is expressed through the face. but also through the voice and, and the way the tone of our voice and so on. that's why it's so difficult for her to react appropriately. the same word or the same sentence can come across very differently depending on the mood, the occasion or the person we're talking to. unfortunately, there's no use a manual for humans that fur hat can learn for all yet. anyway, there's plenty of cases where, you know, a face can be identical and the same features, but the context, the body and the voice dramatically changes how we understand that person. there's all sorts of different kinds of cues. in terms of intonation, pitch, contour, or format, characteristics that change how we perceive other people's voices, the emotions that they're feeling, their intentions. how do we read moods? mark sheds is researching how tiny movements in our facial muscles can influence our communication with the eyebrows, cheeks, lipsynching all contribute to forming very different types of smiles with subtle because it has to do with micro expressions that you see around the i region or the mouth region, or you can face my like if i, if i do this in the faith matter, you can see that the birth is pretending to be happy or being cynical or sarcastic, but it's not revealing what, what, what his or her true sentiments or emotions are. and it's not only smiling, it's so also in the, in the very subtle movements of eyebrows. a very subtle movement of blinking a recent u. s. t. v shows focused on body language lightman. the protagonist of the crime shows lie to me. he was an expert in micro expressions who believed facial expressions could expose lies and suppressed emotions, huge shame and shape contempt. these expressions are universal. can we really identify every single emotion just by practicing? some scientists think. so apparently, all we need to do is consciously notice each millisecond long facial expression. the results are used in market research to find out which commercials and most effective, especially trained security teams at airports. also analyzed facial cues, spock potential terrorists you will be really that easy to tell when criminals align spending. hollywood wants us to think so. 43 muscles combines produced possibility of 10000 expressions. now, learn them all. you know, polygraph, how much did we spend on this damn project? but the scientific world takes a slightly dim. if you, in real life, it's often much harder to do. so for instance, there are these planes that from your micro spaces you can see whether someone is lying or not. but that's close to impossible. so for most kinds of people lie about something. if you're close to chance level, about guessing whether or not someone is speaking the truth. and ironically speaking, if your life becomes more important, like if i'm lying about something which is which reading mattress, like i have to hide something it's called the pink elephant effect. your queues 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 much ferris is looking to children aged 5 and over for the and so yeah, the children are asked to tell the prince and computer game and 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 children's behavior in an attempt to find any differences in the back after recording numerous children, the results highlight signs the point to lying. derek is a lot more you don't do the slot when you look at the face when they're being truthful, they are very open, but they just kind of expression when they're being when they're lying and they have depression that they're being watched and being observed. you see that they have this sense of all i'm 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. it's 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 it's like talking a little bit like this. but not every child showed the same cues. so it's not a reliable way to tell if they are telling the truth or not. ah, generally, we're 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 mean everything is controlled quite different parts of the brain. you're 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? parent schuler is conducting research using a range of different voices group. although the group doesn't agree on everything, the data shows some clear tendencies. artificial intelligence is being used to help identify them from if my mom's minded, if he's of us. my theory is that if a human can hear something or a computer can pick up on it to own guys the have to vote or that it becomes a little spooky in home when we got beyond what a human can spun. oscar grandmother mentioned while m as in her and grunted as i was when i was trying to assess whether the speaker has cove at 19 on all special ha class for yes or and minus for nor would i michel, minos covered no one's him. 3 z nora window so no good. i've got one vote for positive sunday. it was negative. the come to me is the next voice at her eyes. this roy for a month to life, we now have 3 positive. some one negative popped up. i'm going to say positive figure politic maurice newbies. yes, that's right. diagnosing cove, it by simply listening to someone's voice, sounds risky, at least when we rely on the human ear. at the start of the pandemic, we own shuler, programmed a range of voices into artificial intelligence is a more accurate diagnosis now possible. veronica smith, this is the a symptomatic, negative counters, negative grid from the ribbon. so the loss is the symptomatic positive k l e. in one of us, one of here to most little social's you'd sent his elbow to renew his and his, the hours could pick clouds for we can see quite clearly on the right of the upper tides, dark for washington. his host is in ms. ha ha, there are lots more signals we can use to gardening, like the uncontrolled vibration of the vocal chords that leads to irregularities and the stimuli of a certain throat. now somebody breathlessness is out of the cause as long a speech brightened you to one of the music opened and an old woman of close musical annoy confusion tis at all. wicked could love tom, the signaling of his passport and sadness. once upon the thing, 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 us more occurred on an upcoming dentist. at least 85 percent of the diagnoses made by artificial intelligence were correct. what's more, computers could also identify a d, h. d parkinson's out farmers and depression by analyzing voices. anything that goes wrong in the body or brain impacts our voices. to make a diagnosis, official intelligence looks at up to 6000 different vocal cues. ah, the new technology could allow diagnoses to be made more easily. and early on 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 love to 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 it's 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 prob 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 this person figure something often does something of happiness in yourself. like if you, if you see a smiling person, you sometimes start to smile yourself. and so i don't know, maybe one of the attractive feature of the mona lisa is exactly to do with that. like there's something intriguing, something attractive about looking at the painting because she elizabeth smiled. 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, nice fatty last. her audience reacts. similarly, they smile back, not in agreement and give positive feedback. oh, i see 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 it's not just our facial cues that sink. it's our voices to try to express an emotion vocally that we're not feeling is nearly impossible to 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. it's not what we say that counts. it's how we say it and stem is an old lovely good voice is an extremely complex, multi layered signal it only, but for savings will 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 indication which part the conversation are important as calm as need to consider short pauses to em, versus this dish versus one big dish. and in fact, argue people who communicate likelihood are regarded as more likable. demant is more visibly eoc, a mot. oh, that's it with. so it's all about how we use our voices to package the content. did you know, one of the fun edition is performing a short test tracking of how well can his coworker present a text his reading f
