Flown back to the uk. Judith moritz reports. They flew all over the globe for thomas cook, now their world has come crashing down. Jobs gone, livelihoods destroyed. When the airline folded, jo was one of the cabin crew left stranded abroad. When she got home, things went from bad to worse. Im now homeless, my landlord is now demanding i leave the property, so i am having to wait for the local council to see if they can put me in sheltered accommodation. So you cant pay the rent, the landlord has not been sympathetic . No, hes not being sympathetic or compassionate or anything, he just wants me out. Is it here that we sign for the redundancy courses . There is some union help available and thousands of staff are now starting legal action to claim the lost wages. These cabin crew posed for a photo on what would be their last flight. Amongst them, jenna, who was made redundant with Monarch Airlines two years ago and is in the same situation again. Its like reliving the whole nightmare again. Its just brought back all them feelings of losing myjob. It was a sunday night, middle of the night, finding out, waking up my family to tell them that the company that i loved as well had gone. So its just a really difficult time to relive the whole process again. No longer in use by thomas cook, during the summer these check in desks were absolutely buzzing and that is what many of the cabin crew i have spoken to today have said they dont understand. How can it be, they want to know, that when they were working on full plane after full plane, their company has gone bust . Many are owed seven weeks pay. Hundreds turned up to Union Meetings at Manchester Airport today, angry and bewildered. I put my uniform on today and as i got to the airport i started to cry because i thought, im coming here in a uniform and ive got nowhere to go. We didnt get a letter through the post. We had a Conference Call on monday. It wasjust dial this numberand listen in. Ill take a few questions. Ok, thats enough now, no more questions. Over and out, phone down. So thats how we found out. They say they put their hearts and souls into thomas cook and with Little Information or remorse this is how the company has repaid them. Now in a few minutes itll be time for newswatch. But first, heres click. Thursday was bbc music day, an annual celebration of the power of music to change lives, with 2000 events across the uk and 100 broadcasts on tv, radio, and digital. But its important to remember that not everyone experiences sound in the same way. For example, this week is International Week of the deaf. So we met twins hermon and heroda berhane. Now, theyre both deaf, and although they love dancing and they love going to deaf raves, theres obviously a lot about music which they dont experience until now. We joined them when they tried on a prototype shirt which can turn music into a whole body experience. Sound is something thats around all of us all the time. When we identify those sounds as signifying danger, weve evolved to recognise those sounds and react to them. In the modern world, we have become ever more used to isolating ourselves from the world around us. For most people, recognising those sounds is something we do every single day, but getting devices to recognise different sounds is something that has traditionally been challenging. Now, one uk based Company Claims to have cracked that problem. Audio analytic has developed a new technology to recognise a wide range of sounds that can then be used as a trigger for a number of different actions. Now, what this technology does is it uses Software BasedArtificial Intelligence to identify and recognise everyday sounds. And it can be integrated into a number of products. Ill show you a couple of examples of how it might work. One common application is in headphones. Walking down the street for example, there is an angry dog nearby. Barking. Speaker caution, there is a dog nearby. Increasing transparency. So what it would do in that situation, it would recognise a dog barking, lower the music or cut it out altogether in your headphones and warn you there is a dog nearby. Another application it would have is in smart speakers, most of us have these things around the home now, and it can be arranged to listen passively for things like a baby crying. Baby crying. Fundamentally, sound recognition is very different from speech recognition, and we have had to come in and solve some of those fundamental differences. Baby crying sounds very different to another baby crying. There is a huge diversity from when they are six months old through to when theyre two years old. But all of that we refer to as baby cry, so there is some commonality, and we need to teach those machines that commonality. But as we know, ai can only ever be as good as the Training Data it works with. So they have to capture these sounds live. Naturally, we wanted to witness this first hand. And what better way to start than with a couple of very good dogs. This is an anechoic chamber, or in this case, a semi anechoic chamber. It is designed to absorb sound. We are here to record these two beauties, hopefully barking on demand. Barking. These waveforms i can see on this screen are the representations of what is coming off the microphones in there. And in the middle is the actual dog bark threshold that the system is listening for. And when it identifies them, you should hear it activate. Speaker hey monty, i can hear you barking. As it is late and you are home alone, i am going to alert your owner, turn on the lights and place onjazz, because i know how much you like it. Nice. But dogs, as good as they are, are only the beginning. The space here can be used to record anonymous range of sounds, ranging from the dramatic. Siren wails. To the more low key. Bell rings. There is no shortcuts to this, it is literally, you have to have the data set. We have to go and collect all the data, so we have the Worlds Largest collection of audio data, 15 million audio event files, that help us train the technology itself. And of course we couldnt leave without taking a sledgehammer to some windows. Glass smashing. All in the name of technology, of course. The ziggo dome, amsterdam. Performing here is the legendary sir elton john, currently on his farewell tour. But he has added a Little Something extra to each night and it is called peex. It is a device that allows you to mix live music as it is being played in front of you. Boost the volume of instruments, listen to nothing but eltons voice, but how does it work . Benny and thejets. First of all the music is recorded onto peexs system where it breaks down the 95 channels of audio coming from the stage into five different musical categories. Those five mixes are then sent all the way here to the back of the hall and sent out again as radio waves by these transmitters. But to make sure that everyone gets a signal, five more transmitters have been permanently installed above the stage. And a tiny microphone on the device listens to what is being played on stage, so it can sync up with the mix that your device is being sent, so when you adjust the levels, it will be in real time. Right, elton is about to start performing. Lets see how this thing fares. Full band plays. Guitar only. Organ only. Drums only. Wow. That sounds great. The vocals are crisp, the guitar, you can really hear it, but because i am too close to the stage, i cant really distinguish what im hearing on stage and on here with the drums. So what im going to do is go to the back of the hall and see how it fares there. It works even better further back from the stage. And to listen to the mix you make, you are given normal earphones instead of noise cancelling, so you dont lose out on hearing the atmosphere too. For people who are hard of hearing, which essentially you do have locations in the concert hall where they can come and hear, this allows them to actually be anywhere in the concert hall. Peex is not for everyone. There are people who already have superior sound quality and they do not wish to have it improved, but there are people who want to experience concerts in a different way, so it is really allowing for everyone to opt how they want to experience the concert. And that is what we found. Not everyone enjoyed using it. It is an amazing system, and i even let people next to me listen to it, but it is like, you have to be very sure of yourself to use that system as an artist. Laughs. The music was very loud, you have to put that even louder, so its going to be like. Like you have nails in your ear. So, as innovative as this kit is, it may not be for you. You mayjust want to go to a concert and experience it organically. But having the option to mix your favourite artist while they perform in front of you, this might be a new direction in live music. Drums play. Set for the shortcut of this audio tech special. Plenty more in the full length version which is available now on iplayer. Dont forget that throughout the week you can find us on facebook, youtube, instagram and twitter at bbcclick. Thanks for watching, thanks for listening, and we will see you soon
