here at the top of the hour. now on bbc news, click. this week, we talk talk. - can your voice what this week, we talk talk. - can your voice - what i wrong this here you? you all please stop shouting? —— can this helmet hear you? alexei, what are the amazon spheres? the amazon fears are three the record conservatives on the

headquarters campus of amazon in seattle, washington. they are an unusual place to work, i have to say. the dome sales 40,000 plant. they also have waterfalls, meeting spaces and shops. they are slightly tropical, quite moist, and give you a real sense that you are working in the future. i mean, who would have thought in the middle of seattle there would be a rainforest? and amazon are go for an amazon ra i nforest? amazon are go for an amazon rainforest? they amazon, think what? jungle? 0nline shopping? 0r rainforest? they amazon, think what? jungle? 0nline shopping? or do you think of alexa? this is after all the company that is ripped like a football —— brought voice control to the masses? anyone, young or old in any country in any context can use natural language to interact with technology. you can tell me to play

music, create a list, set reminders or look upa music, create a list, set reminders or look up a topic on wikipedia. alexa will only be a successful as the partners are that support it. and that is why voice is the next battleground for the texts of the giants of the more voice applications that are of the more co mforta ble applications that are of the more comfortable we are talking to them, the more they will integrate themselves into our lives. just this week in fact alexa's voice started sounding more human, developers using artificial intelligence techniques to learn from news broadcast how to tone and emphasise words in a sentence. american brides are continually looking for ways to personalise their wedding to reflect their own style. now, as a human being, you will know that you can tell quite a lot from someone's voice, notjust tell quite a lot from someone's voice, not just what they mean tell quite a lot from someone's voice, notjust what they mean but also how they are feeling and possibly whether they are ill. it is obviously really hard to a computer to do but nick has been looking at

some technology that is working towards just that. i've come to tel aviv, israel, to see at a with a difference. no cold stethoscope but i do need to say saykara of all is making other sounds. -- ahh. it is the early decay of the voice. today the early decay of the voice. today the doctor is going to give me my medical purely by listening to the way i talk. verbal of what my state of health is. he is a firm believer it isn't what you say but how you say it. speak foreign languages. all of them are ways of expressing love. and if i am commending you and it is the same in all languages. he isn't a doctor of medicine but of research. we have been working on it for more than 24 years which has

culminated in a new piece of software. it is a tuesday morning, we haven't to catch a flight later back to london. by analysing my postal integrations, he says his algorithm can infer my mood, attitude and personality. you are ambitious, you are curious, a little bit adventurous, and a little bit conservative. it is something in between. i feel like i am getting my palm read. 0k! and the graph is saying, oh, you are very tired.|j palm read. 0k! and the graph is saying, oh, you are very tired. i am very tired! of the reason i am here is the something far more important because the doctor says his system can also be used to diagnose whether i have the disease. and even how bad it is, just by listening to my voice. we can - the early signs yong—g; x; 41:24; §;~l§—'§£ q? heart yong—g; x; 41:24; §;~l§—'§£ =¥wfi heart problem, of parkinson's, heart problem, autistic signs of

autistic children. early signs of prostate cancer. he is comparing the audio wave patterns of someone's voice against an archive of recordings of people with no illnesses. how are you analysing those wave patterns? you can see there is a weakness in this area, you can see the same creator but also here. these are the signs of an ill person and you can see decay of the voice, deterioration, is ill, tired, cannot express himself well, if you are combined all the signs together, we can see how severe is problem and what is his problem. a p pa re ntly problem and what is his problem. apparently the system is 75% accurate and can tell you the severity of your condition. if for

real integrating the technology into listening devices could change the way we interact with our gadgets. further down the road, without technology, these machines would also be able to tell me, something is different with your health condition, maybe you want to go into another checkup, maybe it will let my doctor know about this. so from the voice, there is so much information that can begin and we arejust at information that can begin and we are just at the beginning. 0k, reality check time, because as amazing as it sounds you may be thinking this is all too good to be true. at the thing is voice is already used to diagnose certain conditions and medical professionals to see that this could have more potential. in london, iwent to see that this could have more potential. in london, i went to meet a dock, a cardiologist at hammersmith hospital, and honorary senior lack at imperial college london. there was no doubt that doctors use patient‘s voice is as a way of diagnosing certain conditions

and their own neurological disease and their own neurological disease and their own neurological disease and the motor neurone or parkinson's that has characteristic changes to the voice to help us make a diagnosis. but it would do a voice's potential, today beyond a bill has had on the one paper published in conjunction with the us —based mayo clinic, investigating the connection between voice and colony after a disease. what this study has done is attempted to make a diagnosis of c0 i’o nary attempted to make a diagnosis of coronary artery disease using the voice alone, it is a completely new avenue and i would be the technology at present needs a lot more work. the study being published doesn't give us definitive proof that this technology can make the diagnosis. the study has been formed in a highly enriched and highly selected group of patients and actually i would say the capacity of voice to be able to detect the severity of an individual legion as they propose is a little far—fetched. individual legion as they propose is a little far-fetched. california —based telly medicine start—up has been operating the mood analysing system into its gp appointment at.

0ne second, there with me while i bring up your data. while the doctors listen to problems over video call, the software can inform them about the patient‘s emotional state. how accurate is beyond verbal around the mood? very. how is accurate regarding the acute culinary signal? we don't know yet. but in the race very good feel about it but me as a doctor cannot trust they feel, i need to trust real correlation or real demonstration. beyond verbal isn't the only business claiming to understand our hellfire voice, healthy mites ibm and some other companies and research in the connection between voice patterns and disease. we believe that we are better than 75% in many decisions however it is still not enough to say that is it, it is still enough to say alert, ta ke it is still enough to say alert, take care of yourself, go to the

doctor, make other checks. having potentially inaccurate health warnings at our fingertips could come with a percussion is. and do we wa nt come with a percussion is. and do we want the tech giants to know so much about us? the problem with anything thatis about us? the problem with anything that is predicting a disease process is that it can be wrong or sensitive --if is that it can be wrong or sensitive ——if sensitivity is not high enough oi’ ——if sensitivity is not high enough or it is not specifics it will often make diagnoses when there isn't a particular problem or it will over diagnose problems that don't need any investigation said it would be a concern to me as a dock that we end up concern to me as a dock that we end up testing too many people and it would also be a concern to patients because they may end up being told they have a problem when actually there isn't a concern. further trials are being conducted in israel, china and soon the uk. and while the main be simply sci—fi, the idea of alex in the future are letting me about my health is at once appealing and yet unsettling. —— alexa. hello and welcome to the week in
