The idea of the project was raised by Swetha Machanavajhala, a Microsoft developer who has hearing loss. Her neighbor complained about the loud sound coming from Machanavajhala’s carbon monoxide detector. Thus, Swetha and her team designed an app for connecting people with the world of sound. It uses the people with hearing impaired’s interest in emotional information to visualize the intensity and direction of the sound. And it provides the ambiance of the sounds around them. It also has the function of notifications and speech-to-text.
In fact, the function of Live Transcribe is extremely simple. The main page is basically nothing but the current transcript of speech. Some deaf friends are not convenient to speak, you can open the built-in keyboard, input their own words to each other to see. Through environmental sound recognition, you can also see the sound of knocking, running water. In our communication with the deaf community, we've learned that sometimes they leave the tap on and leave it on, or someone knocks on the door and doesn't realize it, and that's where it comes in. The advantage of Live Transcribe is its simplicity. There are not uncommon products for voice recognition, but none that are designed specifically for deaf people, that can be opened immediately and transcribed without interference, and that are extremely easy to operate.
It's a smart wearable device that helps people who have had their vocal cords removed because of cancer recover the sounds of the past. Approximately 300,000 people worldwide lose their voices every year due to causes such as laryngeal cancer. One way to get your voice back is through a machine called an electrolarynx (EL). One hand is blocked when talking using EL. Moreover, it produces only a monotonous robot-like sound. This cylindrical design has not changed for more than 20 years.To solve these problems, we made Syrinx, a new type of hands-free EL. The neck-brace design enables hands-free usage. To generate a more user-like voice we worked on the vibration pattern of the device. These patterns highly depended on the user's voice. So we used voice processing tools to generate the vibration patterns from the user's voice.

The project is an interactive installation reacting in real time to the uers’ hands, allowing the writing of a sound and light sentence through its movements. With an awareness-raising approach, the goal is not to introduce people with the sign language, but make them feel the articulation and issues of it through accessible representations, for deaf people but also for people who don’t know sign language.
Sign-IO is an assistive wearable technology that translates sign language to speech. It comprises of a pair of gloves, which capture the sign language gestures. And a companion mobile application that is paired to the gloves via bluetooth. The emobile app vocalizes the signed gestures in real-time therefore enabling seamless communication between sign language users and non-sign language users. Sign language is a form of communication predominantly used by deaf people or those with hearing impairments. However, communicating with people without hearing impairments or with those who are unable to sign can be genuinely difficult. Kenyan inventor Roy Allela sought to solve this problem by creating the Sign-IO glove. Inspired by his deaf niece, Allela created a glove that is able to translate sign language into audible speech. Using integrated sensors, the glove reads the hand movements of the person signing, it then transmits this information via bluetooth to a smartphone.
This AI-powered robot comes with an integrated smart home system for seamless and reliable use through the day. One of the components is the hearing clock which wakes you up with vibrations while the Hearingbot smart home system raises the curtains for you. A cool feature is gesture recognition which makes communication easy for those who rely on sign language. The robot can recognize the signs and uses speakers as well as subtitles to communicate with its user. “It interprets sign language of the deaf through motion sensor and projects it into a projector. It can be paired with different products, for example, Hearingbot will manage the cooking status and schedule of the dish while the hearing-impaired person cooks and prepares the dish individually.
Designed to help the hearing-impaired speak correctly (while also making sure their vocal muscles don’t atrophy with lack of use), Commu is a two-part device designed to capture vocal-chord vibrations and translate them into speech, guiding the user through the process of enunciation and pronunciation. One half of the Commu sits on the throat, with a vibration-sensor capturing the nuances of the waves, to translate them into text. The other half of the Commu docks your phone, allowing it to display your speech waveforms, as the phone’s app uses AI to determine whether the sentences spoken were clear or not. Gradual progress helps users retain powers of speech even though they can’t hear speech on a day-to-day basis!
The Feeling Mouse, designed specifically for the hearing impaired, appeals to the user’s tactile senses to emphasize the all-important “click” that’s crucial in operating the device. When the user presses down on the mouse, raised bumps slightly protrude through designated holes where the user’s fingers rest to signal the “click.” It’s a simple solution, but incredibly useful for those missing out on this subtle queue.
The VV-Talker is a device designed for deaf children to help them overcome their problem in speaking effectively. If you can’t hear the sounds you make, it’s difficult to know if you’re pronouncing it correctly. The device has a screen attached to a wand. Sounds are associated with vibrations. As the child speaks, the device provides feedback on accuracy and teaches the child to speak with the correct “vocal vibrations” to achieve the correct modulation.
Acoustic Poetry is an exploration in the design of products for deaf culture that focus not only on simple functionality but also offer an emotional connection to the acoustic environment that would otherwise be limited. Through the device, the user broadcasts the sounds of the environment that has sparked their curiosity to an interpreter who then responds with a brief verse describing the atmospheric noises. The result is an enriched connection to both everyday experiences and special occasions.
A view of the ambient noise is what this device hopes to give people with less than a perfect sense of hearing. The fashionable bit of the Danger Alert Enabler, is the wristband, but it also comes with a “micro device.” The way these two bits work together is: sound goes in one, comes out the other. But as the micro device, which sits on your belt, hears sound, it interprets it and translates it to a corresponding pictogram and in some cases, a vibration for warning.
In nature, the device can show you a bird, a sheep, an oncoming thunder or rainstorm, the sound of water, and more. In the way of ambient sounds, the device can show you the telephone, some music, some chattering voices, and more! Then there’s DANGER!
A common misconception about the hearing impaired is their inability to experience the joy of music. They may not hear and process sound audibly but they certainly can feel it. In fact, studies have shown the sense of touch is heightened allowing them to perceive music in a totally different way. SOUNZZZ is a visual, audio, tactile MP3 player designed for the hearing impaired but universal enough for all to enjoy. Sound is translated into a series of vibrations. One hugs the device to feel the music and it even plays an equalized light show along with the sound. A very unique device I would love to see on store shelves.

Assistive Technology for the Hearing-Impaired, Deaf and Deafblind by
Affirmative legislative action in many countries now requires that public spaces and services be made accessible to disabled people. Although this is often interpreted as access for people with mobility impairments, such legislation also covers those who are hearing or vision impaired. In these cases, it is often the provision of advanced technological devices and aids which enables people with sensory impairments to enjoy the theatre, cinema or a public meeting to the full. Assistive Technology for the Hearin-impaired, Deaf and Deafblind shows the student of rehabilitation technology how this growing technical provision can be used to support those with varying reductions in auditory ability and the deafblind in modern society. Features: instruction in the physiology of the ear together with methods of measurement of hearing levels and loss; the principles of electrical engineering used in assistive technology for the hearing impaired; description and demonstration of electrical engineering used in hearing aids and other communications enhancement technologies; explanation of many devices designed for every-day living in terms of generic electrical engineering; sections of practical projects and investigations which will give the reader ideas for student work and for self teaching. The contributors are internationally recognised experts from the fields of audiology, electrical engineering, signal processing, telephony and assistive technology. Their combined expertise makes Assistive Technology for the Hearing-impaired, Deaf and Deafblind an excellent text for advanced students in assistive and rehabilitation technology and to professional engineers and medics working in assistive technology who wish to maintain an up-to-date knowledge of current engineering advances.

Sound-Based Assistive Technology by
This book presents a technology to help speech-, hearing- and sight-impaired people. It explains how they will benefit from an enhancement in their ability to recognize and produce speech or to detect sounds in their surroundings. Additionally, it is considered how sound-based assistive technology might be applied to the areas of speech recognition, speech synthesis, environmental recognition, virtual reality and robots. The primary focus of this book is to provide an understanding of both the methodology and basic concepts of assistive technology rather than listing the variety of assistive devices developed. This book presents a number of different topics which are sufficiently independent from one another that the reader may begin at any chapter without lacking background information. Much of the research quoted in this book was conducted in the author's laboratories at Hokkaido University and University of Tokyo. This book offers the reader a better understanding of a number of unsolved problems that still persist in the field of sound-based assistive technology.

Shouting Won't Help by
For twenty-two years, Katherine Bouton had a secret that grew harder to keep every day. An editor atThe New York Times, at daily editorial meetings she couldn't hear what her colleagues were saying. She had gone profoundly deaf in her left ear; her right was getting worse. As she once put it, she was "the kind of person who might have used an ear trumpet in the nineteenth century." Audiologists agree that we're experiencing a national epidemic of hearing impairment. At present, 50 million Americans suffer some degree of hearing loss--17 percent of the population. And hearing loss is not exclusively a product of growing old. The usual onset is between the ages of nineteen and forty-four, and in many cases the cause is unknown. Shouting Won't Helpis a deftly written, deeply felt look at a widespread and misunderstood phenomenon. In the style of Jerome Groopman and Atul Gawande, and using her experience as a guide, Bouton examines the problem personally, psychologically, and physiologically. She speaks with doctors, audiologists, and neurobiologists, and with a variety of people afflicted with midlife hearing loss, braiding their stories with her own to illuminate the startling effects of the condition. The result is a surprisingly engaging account of what it's like to live with an invisible disability--and a robust prescription for our nation's increasing problem with deafness.

An Assistive Hand Glove for Hearing and Speech Impaired Persons
Communication is more than spoken language; it is a way of expressing ones thought, ideas and messages. Communication for them has become a great challenge especially the need to communicate with normal people in their daily routine. Hearing/Speech Impaired persons used hand sign language as their language of communication; however, it will only be effective if the person they are interacting with knew the hand sign language. This study developed an assistive device for persons with hearing/speech impairment. The system was designed to interpret their signs or gesture into a corresponding message which were preloaded in the device. The device produced a voice-based message through the audio module and displays the message in LCD. This study was basically a glove based system and a microcontroller based system. Flex sensors, Gyroscope and Accelerometer were incorporated in a glove that can identify the sign language and an Arduino Nano microcontroller unit converted these gestures into voice and text output. The result of the Assistive device during its test-experiments showed that the system can recognized the hand gestures with male and female voice output on each hand gesture with an overall accuracy of recognition of 83.58%.

Haptic sound-localisation for use in cochlear implant and hearing-aid users
Users of hearing-assistive devices often struggle to locate and segregate sounds, which can make listening in schools, cafes, and busy workplaces extremely challenging. A recent study in unilaterally implanted CI users showed that sound-localisation was improved when the audio received by behind-the-ear devices was converted to haptic stimulation on each wrist. We built on this work, using a new signal-processing approach to improve localisation accuracy and increase generalisability to a wide range of stimuli. We aimed to: (1) improve haptic sound-localisation accuracy using a varied stimulus set and (2) assess whether accuracy improved with prolonged training. Thirty-two adults with normal touch perception were randomly assigned to an experimental or control group. The experimental group completed a 5-h training regime and the control group were not trained. Without training, haptic sound-localisation was substantially better than in previous work on haptic sound-localisation. It was also markedly better than sound-localisation by either unilaterally or bilaterally implanted CI users. After training, accuracy improved, becoming better than for sound-localisation by bilateral hearing-aid users. These findings suggest that a wrist-worn haptic device could be effective for improving spatial hearing for a range of hearing-impaired listeners.

Efficacy of an Assistive Device for Museum Access to Persons with Hearing Impairment
Museum is a place of learning. Visit to the museum will be fruitful through effective interaction with the curator. Acoustic barriers in the museum prevent the curator's speech being intelligible to persons with hearing impairment. An assistive device was developed at AIISH to overcome the acoustic barriers for museum visitors with hearing impairment. The field trials of the device were conducted at the Regional Museum of Natural History, Mysuru. The study reported in this paper quantifies and critically evaluates the efficacy of the device in overcoming the acoustic barriers and making curator's speech audible and intelligible to the visitor. The efficacy measures employed were measurement of acoustic variables and feedback of the user through questionnaire. The results showed that, the device has been effective in overcoming the acoustic barriers for all visitors with hearing impairment, irrespective of their degree of hearing loss and the type of the hearing aid. The device has followed a universal design and hence is useful to all visitors to the museum.

User-Innovated eHealth Solutions for Service Delivery to Older Persons With Hearing Impairment
The successful design and innovation of eHealth solutions directly involve end users in the process to seek a better understanding of their needs. This article presents user-innovated eHealth solutions targeting older persons with hearing impairment. Our research question was: What are the key users' needs, expectations, and visions within future hearing rehabilitation service delivery? Method: We applied a participatory design approach to facilitate the design of future eHealth solutions via focus groups. We involved older persons with hearing impairment (n = 36), significant others (n = 10), and audiologists (n = 8) following 2 methods: (a) human-centered design for interactive systems and (b) user innovation management. Through 3 rounds of focus groups, we facilitated a process progressing from insights and visions for requirements (Phase 1), to app such as paper version wireframes (Phase 2), and to digital prototypes envisioning future eHealth solutions (Phase 3). Each focus group was video-recorded and photographed, resulting in a rich data set that was analyzed through inductive thematic analysis. Results: The results are presented via (a) a storyboard envisioning future client journeys, (b) 3 key themes for future eHealth solutions, (c) 4 levels of interest and willingness to invest time and effort in digital solutions, and (d) 2 technical savviness types and their different preferences for rehabilitation strategies. Conclusions: Future eHealth solutions must offer personalized rehabilitation strategies that are appropriate for every person with hearing impairment and their level of technical savviness. Thus, a central requirement is anchoring of digital support in the clients' everyday life situations by facilitating easy access to personalized information, communication, and learning milieus. Moreover, the participants' visions for eHealth solutions call for providing both traditional analogue and digital services.

AUDIS wear: a smartwatch based assistive device for ubiquitous awareness of environmental sounds
A multitude of assistive devices is available for deaf people (i.e. deaf, deafened, and hard of hearing). Besides hearing and communication aids, devices to access environmental sounds are available commercially. But the devices have two major drawbacks: 1. they are targeted at indoor environments (e.g. home or work), and 2. only specific events are supported (e.g. the doorbell or telephone). Recent research shows that important sounds can occur in all contexts and that the interests in sounds are diverse. These drawbacks can be tackled by using modern information and communication technology that enables the development of new and improved assistive devices. The smartwatch, a new computing platform in the form of a wristwatch, offers new potential for assistive technology. Its design promises a perfect integration into various different social contexts and thus blends perfectly into the user's life. Based on a smartwatch and algorithms from pattern recognition, a prototype for awareness of environmental sounds is presented here. It observes the acoustic environment of the user and detects environmental sounds. A vibration is triggered when a sound is detected and the type of sound is shown on the display. The design of the prototype was discussed with deaf people in semi-structured interviews, leading to a set of implications for the design of such a device.
