1 of. the. grammys fighting over. the fight. well speech be the new intersection between humans and technology even twitter is setting its hopes on audio messaging now even twitter setting its hopes on audio messaging now how well does most recognition work and what else does our voice reveal about us voice command and voice analysis our topic today on shit.

asking the french for recipes talking to your g.p.s. or turning off the lights with your voice turn off the lights digital assistance using voice command infiltrating our day to day lives but why always so keen to encourage this is a fact and his berlin based start ups you all for has developed an open source platform that anyone can use to program voice apps which work on all devices. is not what i'm trying to pass anything about voice is how natural this type of interaction it. comes from but even a 3 year old child can ask for a specific song although it can't really help the i'm not going outside to tell you know it's real and then there's the older generation who never quite felt understood by technology to. all of a sudden they see more free interacting with tech and this had never quite worked before. this example shows just how much it's already possible the 2 people don't

speak the same language but they can still communicate thanks to smart speech software which they was going to let bulger set and as a unit of course i'm looking for a place to have lunch before going to the airport there's a great place around the corner you can take the train from there to the airport when you look at it that way that they live with this don't mind it is the i.d.'s they light up way to go. but it's not as easy as the advertisement might have you believe i know this from my own family my father speaks german with an accent and the speech recognition technology of the remote control often struggles to understand his commands this has to do with who developed the algorithms and crucially with who didn't. pashto and yelling speech impediment dialects different cultural backgrounds. there are many people who don't sound like the average silicon valley coder develop a whole community and there are often comprehension problems it's. all tyros out

also just from differences between genders holland is oft women are frequently understood less well than men for example. these differences are largely due to the data used to train voice algorithms the typical software developer is a white man who speaks english. in the beginning developers use their own voices to train the voice assistance a circumstance which still has consequences to this day. no voice assistant whether produced by amazon or google apple i.b.m. or microsoft will understand every word but the error rates follow notable patterns a study by stanford university for example found a 35 percent error rate for african-americans as opposed to 19 percent for white americans even though english is the standard language for voice systems many languages can't be used at all it's just 8 work across platforms for amazon google and apple the google smartphone assistant is the most i've ever seen it speaks 44

languages but generally the rule for all devices is minorities are not a certain time or today. if you lend and in many countries all there's no speech software us off because the demand just isn't worth investing in at the moment on the move. so speech recognition systems don't work the same for everyone plus let's not forget that there are people with speech impediments and people who cannot speak or hear a german research project has developed the 1st tour that enables speech software to recognise language research is also focusing on going beyond the strict sense of for its meanings after all it's not just what someone says but also how they say it that plays a big role in comprehension this is a spell. intriguing for companies as they hope to find out more about their customers. i'm in a great time today i know. it takes only a few words to hear what kind of mood a person is in whether they're happy or angry. ai program can

filter out 6000 for amateurs from someone's voice including pitch and tambor. developers from the start of my dear again munich are hoping that their smart voice analysis will enable them to sneak a peek into people's hearts. the software has already been tested in call centers where there's been you something coming calls to analyze the callers as well as the staff members of the what is this new school assistance for control . using the software i felt as if i were automatically looking at things from the outside modest when i was and i thought about the customer a lot more. happy customers are loyal customers and companies want to keep it that way but they're also critical voices in increasing creating voice space profiles is problematic one is going to get you to lecture and digital ethics and. a voice can reveal a lot about my mood or my house phone bill was fixed those are very sensitive private

status and even they should be of no concern to companies and at least not so long as i have not given my explicit consent. but that's what companies want to find out as much as possible about their customers from their voices since 2018 amazon has a patent on advertising and for people with illnesses or conditions in other words alexa is supposed to tell from a person's voice whether they're ill or even depressive and then recommend products accordingly but how is it that this technology can work to speak we need our entire body that longs the trachea and the larynx with its vocal cords in total more than $100.00 muscles a part of creating sound and several parts of the brain too and that. the reason why our voice can reveal important information about illnesses like parkinson's. compared to a healthy person's voice. someone with parkinson's voice was some chappie.
7:23 pm
7 7 your own show life is a computer scientist into steam or working on detecting parkinson's disease but it's very early stages. you know if you can are concerned there's a neurodegenerative disorders at which specifically attacks the motor functions of the ghost. can be detected some very early on in my muscles i know which we have here you generate sounds and voices in the muslim in the future it may also be possible to detect other conditions like autism depression or currently called 19 through voice analysis incredible what's become possible with artificial intelligence and digital voice analysis but it's worth bearing in mind that this technology also comes with wrists back in 2017 the canadian startup lie a bird called sister with manipulated voices of politicians like donald trump and barack obama i am not a robot my engine nation is always different i'm not a robot my information is always different well that doesn't really sound bad real
7:24 pm
is that why a bird has since then been bought and now it's part of a software for transcribing and creating pod casts the integrated ai makes it possible to edit the voice recordings after you have finished recording like this for example i should probably get in shape this year i've changed this quickly i should probably watch t.w. ship this year that sounds pretty good already but it only works on line and so far only in english but the technology is developing rapidly take the example of this french company which is already working on manipulating voices in real time. french software company candy voice has specialized in cloning boys. since. she home one of what off you'll do our technology can synthesize a voice with just 80 words and then let that person's voice say whatever it wants to. the porter to demonstrate the way the software works the voice experts need

samples i'm going cottons football team achieve the expected results. 500 sentences contain all the typical sounds of german. defense to news clips and in the early afternoon hours in southeast china. an algorithm disassembled the recordings into small fragments the meaning of the words is completely irrelevant here what the program is after is the sound of the individual fragments so that it has numerous sound bites from both speakers. now the algorithm can start comparing the fragments thereby also comparing the tambour of both voices the more words are given to the algorithm the better it can train on its own. once training is complete the software should be able to convert every sentence spoken by the male voice into the female voice and vice versa. but how well does the software work can voices be manipulated life and i'm already on

a 29 years old and i'm from germany i'm speaking in max's voice and it sounds very real. discovered some wish not i was pretty close to what i recorded voice sounds like mckenna. and the other way around. i'm max but i'm speaking in area as voice right now and that's pretty convincing. but also quite a weird feeling. pretty impressive but it doesn't sound good enough to really be able to deceive you scientists are working on using the human voice as a type of password the idea behind that is that register customers would be immediately recognized by their voice when they call. a growing number of companies including european banks watch for a place identity verification for security questions fingerprints and pins with voice authentication. that's a problem hold for instituting dom's dot and southwest germany project head on is
7:27 pm
testing such a voice id system mind you my voice is my password to. a company for instance a bank has his voice samples just as they would for a customer the company software created a biometric profile from his voice sample with more than 100 identifying characteristics such as pitch or rhythm. lynched and when logging in be a voice the program compares the voice speaking with the stored profile if they match the customer's granted access. but what if somebody uses a digitally manipulated voice. denier birds or similar programs have not yet reached a level of protection to be able to accurately recreate a hopeful melody and all the characteristics of a human being's voice. but not all experts are convinced voice verification systems are safe. to aaron see a different way i see voice as an interesting addition adds interest it's not just
7:28 pm
concepts it's interest now i wouldn't use my voice for banking and so on and so much of british actor and i just the technology is only just getting started on the home. so there are still doubts but despite these the tech giants and voice command and analysis as the next major intersection between humans and machines and the technology has already made it into our homes researchers expect that before long our whole apartment or house will be equipped with microphones and speakers so that smart speakers might even become redundant i have to say that i have some concerns about this to mean my apartment is generally a really private place and i don't want to feel like someone or something is listening to me when i'm at home but what do you think about this what do you use voice command for let us know on you tube or facebook and see you soon.
