"[T]he current capabilities of many AI systems closely match some of the specialized needs of disabled people.... Fortunately, there is a growing interest in applying the scientific knowledge and engineering experience developed by AI researchers to the domain of assistive technology and in investigating new methods and techniques that are required within the assistive technology domain."
– Bruce G. Buchanan; from his Foreword to Assistive Technology and Artificial Intelligence: Applications in Robotics, User Interfaces and Natural Language Processing
We introduce a technique for augmenting neural text-to-speech (TTS) with low-dimensional trainable speaker embeddings to generate different voices from a single model. As a starting point, we show improvements over the two state-of-the-art approaches for single-speaker neural TTS: Deep Voice 1 and Tacotron. We introduce Deep Voice 2, which is based on a similar pipeline with Deep Voice 1, but constructed with higher performance building blocks and demonstrates a significant audio quality improvement over Deep Voice 1. We improve Tacotron by introducing a post-processing neural vocoder, and demonstrate a significant audio quality improvement. We then demonstrate our technique for multi-speaker speech synthesis for both Deep Voice 2 and Tacotron on two multi-speaker TTS datasets.
Incredible footage shows the moment a British Paralympian swimmer with cerebral palsy stands up and takes her first steps wearing a robotic exoskeleton. Grace Harvey, 21, was able to take the special walk with the help of state-of-the-art technology developed in Japan -- giving her a day she will never forget. In the video, the swimmer from Ware, Hertfordshire, smiled nervously as she took her'first' tentative steps. She went on to giggle when a bystander said'You're running, Grace.' Swimmer Ms Harvey holds the European record for the 200 metre (656 feet) Individual Medley and is presently the British number one in the 100 metre (328 feet) backstroke event. She is currently training in the city of Suzuka, Japan, ahead of the 2020 Tokyo Paralympics in August.
The advances in technology could mean more for society than just new educational technology and virtual reality video games. People with disabilities are finding innovative ways to put artificial intelligence to work with their current conditions. As the science improves, assistive technology will continue producing new and improved platforms to help create a better standard of living for those individuals. Are you interested in the myriad of ways that assistive technology is changing with the improved status of artificial intelligence? These four examples should give you a great idea of what's possible when you integrate these two fields.
A robotic exoskeleton developed by Korean car manufacturer Hyundai has helped a paraplegic sportsman walk over and hug his mother for the first time in 10 years. Korean para-athlete and pro-archer Jun-beom Park was confined to a wheelchair in 2008 after being involved in an accident as a school boy. He damaged his thoracic vertebrae – the small bones that form the spine – in an incident that left him unable to walk. Now, 11 years on, the archery star has taken his'second first steps' thanks to an'exoskeleton suit' developed by Hyundai Motors Robotics Lab in Seoul, South Korea. In a heartwarming video produced by Hyundai, Jun-beom, 28, is seen putting his weight on his legs to stand up from his wheelchair, aided by the Hyundai Medical Exoskeleton (H-MEX).
Neural network based end-to-end text to speech (TTS) has significantly improved the quality of synthesized speech. Prominent methods (e.g., Tacotron 2) usually first generate mel-spectrogram from text, and then synthesize speech from the mel-spectrogram using vocoder such as WaveNet. Compared with traditional concatenative and statistical parametric approaches, neural network based end-to-end models suffer from slow inference speed, and the synthesized speech is usually not robust (i.e., some words are skipped or repeated) and lack of controllability (voice speed or prosody control). In this work, we propose a novel feed-forward network based on Transformer to generate mel-spectrogram in parallel for TTS. Specifically, we extract attention alignments from an encoder-decoder based teacher model for phoneme duration prediction, which is used by a length regulator to expand the source phoneme sequence to match the length of the target mel-spectrogram sequence for parallel mel-spectrogram generation.
Fox News Flash top headlines for Jan. 10 are here. Check out what's clicking on Foxnews.com A Mississippi Army veteran who served in both Vietnam and Iraq says his prosthetic legs were repossessed and returned in an unusable state -- because the Department of Veterans Affairs (VA) refused to pay for them. Jerry Holliman, 69, told the Clarion-Ledger newspaper that prosthetics vender Hanger repossessed his artificial limbs two days before Christmas. Although he was encouraged to use Medicare to find replacement prosthetic legs, Holliman said he wanted the VA to pay for them.
Delta may be known for its airplanes, but a new and surprisingly dexterous exoskeleton may be their next product to take off. The suit, called the Guardian XO, is a relatively small full-body exoskeleton that the company envisions will be used for heavy duty construction and commercial applications that requires brute strength. In a demonstration of the all-electric suit at CES in Las Vegas - the first ever public demo of the device - Delta and its partner Sarcos Robotics showed off the exoskeleton's capabilities. The demonstrator - a moderately sized young man by the name of Ben - strapped himself into the suit in just a couple minutes and started the first trial. 'It's a pretty comfortable machine, I can move around as if I wasn't wearing this,' said Ben who told the audience that he had only been training with the suit for about four months.
Helping children with attention deficit hyperactivity disorder (ADHD) to focus in the classroom can be a major challenge. Educators might find themselves constantly prompting and redirecting students to perform routine tasks. It can be frustrating for the student and their classmates when their need to move around the classroom disrupts the learning experience. Gains in assistive technology could help to promote better learning for students who struggle with ADHD. Teachers who are growing weary of the constant motion and redirection required for students with ADHD might want to investigate some of these breakthroughs.
Japan's ageing generation is turning to robotic exoskeletons to help them work well into old age, reports claim. The Asian nation has one of the oldest populations in the world, with 28 per cent of natives over the age of 65. As the government considers raising retirement age to 70 in order to cope, more would-be pensioners are strapping on £1,000 exoskeletons to boost strength and stamina to extend their working life. Like most other industrial-focused exosuits it is worn like a backpack but it weighs less than ten pounds and can help lift up to 55lbs (25kg). Exoskeletons are being trialled in warehouses and other labour-intensive jobs to prevent injuries to staff, but have also shown promise in aiding the disabled and elderly.
Older people in Japan are strapping on exoskeletons to help meet the physical demands of their jobs and remain in the workforce for longer. Japan's population is rapidly ageing, with a record 28 per cent of people aged 65 or older. This has led to a shortage of workers, particularly in manual labour industries like construction, manufacturing and farming.
