The current goal for VocaliD, Patel says, is to get more people on their voice donor platform and have them complete the entire list of utterances. Our personalities change what we take on in terms of how we see ourselves across different phases in our lives," she says. "As you grow, you don't necessarily want the same kind of voice. The next question Patel and her company are trying to tackle is how the voice they provide can grow with the younger recipients. And for someone with ALS, it's a task of trying to get to the voice they had before developing the condition. With individuals like Aaron, who've never spoken before, it can be hard to imagine what would be appealing to them and their families. "There could be massive rejection or there could be acceptance." Often, for people that use a device to communicate, if that voice isn't connected to them in way, it's less likely that they'll want to voice their thoughts in discussions.įor Patel, presenting the voices to recipients can be nerve-wracking. She says that voices are more important than we think. But it really needs to feel and fit right to the end user." Because we can get there, we can get close in terms of age, demographics and all that. "It's a very difficult concept to nail and that's why we offer these three choices. Much like beauty, it's in the ear of the beholder. "We don't know what markers are acoustically of what a strong or compassionate voice is." Occasionally, people make requests for a strong or compassionate voice. Last year, VocaliD customized voices for seven recipients but after the company's official launch in August, that number will grow fast. Eventually, the recipient will be able to say anything, including sentences that were not recorded by the donor. Then they present the top three closest matches to the recipient and their family, who then select the voice sample they'd like to have blended with their vocal identity. They find the most fitting voice sample for the recipient, with respect to their age, their height and geography-where they live, if there's an accent. VocaliD uses the recordings to build a model of speech and go on to combine it with as little as two or three seconds of sustained vocalization. These sentences have the sound combinations required to create any sentences in the future. ”ĭespite all the technological advances in his communications software, Professor Hawking used his 1988 Speech Plus CallText 5010 synthesiser until his death.Donors record themselves reading about 3,500 sentences. “It is the best I have heard, although it gives me an accent that has been described variously as Scandinavian, American or Scottish. When I have built up a sentence, I can send it to my speech synthesiser,” Prof Hawking wrote on his website. “ACAT includes a word prediction algorithm provided by SwiftKey, trained on my books and lectures, so I usually only have to type the first couple of characters before I can select the whole word. We read Stephen Hawking’s PhD thesis so you don’t have to Intel partnered with British software company SwiftKey to reduce the number of characters Prof Hawking was required to input before a word was suggested, speeding up the execution of common tasks ten-fold. The new system, which was three years in the making, used an infra-red sensor mounted on his glasses to detect motion in his cheek and trigger word and phrase suggestion. Prof Hawking began to use his cheek muscles to communicate following the degradation of nerves in his thumb, and in 2014 hailed a new Assistive Context-Aware Toolkit (ACAT) platform developed in partnership with Intel as “life changing.” Stephen Hawking will be remembered as one of Britain’s greatest minds (Photo: Getty) He’d once considered using a machine which gave him a French accent, but decided against it as his then-wife would divorce him, he joked. “I keep it because I have not heard a voice I like better and because I have identified with it,” he said in 2006.
