A new complex for connection of a deaf person with a hearing one, which gives an amazing opportunity of real communication.

The complex consists of two Android-devices connected with each other by means of Bluetooth. One of the devices, called “device-D” (Deaf Person), is kept by a deaf person. The other one, called “device-H” (Hearing Person), is kept by a hearing person.

The application for the device-D, called Deaf-Hearing Chat Device D, enables a deaf person to type text messages on a virtual keyboard and to send them to the device-H (the button “Send”). Each sent message can be duplicated by the synthetic speech (the button “Speak and Send”). For the synthetic speech a speech synthesis module should be installed on the device (usually it’s installed; if it’s not it can be downloaded from Google Play, e.g. SVOX classic TTS or Pico TTS). The messages, received from the device-H, are shown on the display.

The application for the device-H, called Deaf-Hearing Chat Device H, enables a hearing person to type text messages on a virtual keyboard or using voice input (the button “Voice Input”). You need an Internet access for voice input. To test the Internet connection quality you should press the button “Test”. To send a message to device-D you should press the button “Send”. The messages, received from the device-D, are shown on the display.
Supported languages for voice input: English (US, UK, Australia, Canada, India, New Zealand, South Africa ), French, German, Italian, Russian, Hebrew, Spanish (Spain, US, Argentina, Bolivia, Chile, Colombia, Costa Rica, Dominican Republic, Ecuador, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru, Puerto Rico, Uruguay, Venezuela), Japanese, Portuguese (Brazilian), Czech, Turkish, Dutch, Mandarin Chinese (Traditional Taiwan, Simplified China, Simplified Hong Kong), Korean, Indonesian, Malaysian and some others.

The exchange of messages is possible in any language supported by your Android-device. Such complex can be used in any country. All messages between the devices free of charge.

Once again, pay your attention that for the use of the complex you need to install the following:
- for the device D – the application Deaf-Hearing Chat Device D;
- for the device H – the application Deaf-Hearing Chat Device H.


This complex gives to deaf person fantastic capabilities for communication. Device-D and device-H connect via bluetooth.
You can choose one or more of the three variants of the complex:
1. phone(as device-D) + phone (as device-H)

This variant is very convenient for constant communication, for those families in which there is a deaf member. Each message is followed by vibration, so one can always call a deaf person, address him (or her).

2. phone (as device-D) + tablet (as device-H)

A deaf person can always have complex with himself (herself). It’s very convenient for communicating freely with the hearing people in public places: shops, hospitals, service centers, etc. A deaf person just hands a tablet to a manager or a consultant, and after that they can communicate freely. The convenience of a tablet is that at its small size its keyboard is big enough, so that everyone can type a big volume of text. It’s better to use a 7” tablet. The convenience of a smartphone is its compactness, and the deaf people usually type messages on its virtual keyboard very quickly.


3. tablet (as device-D) + tablet (as device-H)

This variant can be useful for a services sector, where the deaf people are served. For serving a deaf client the latter is given the device-D, the device-H is kept by a hearing manager, after what they start communicating.
Also, if a deaf person has difficulties with typing messages on a small smartphone keyboard the complex “a tablet + a tablet” will be more convenient.

Review from Laura Hudson

Communication made easier At age 86 my father is completely deaf. Finding ways to communicate was difficult and frustrating for the whole family. Now he can carry his tablet everywhere...restaurants, Dr appointments, shopping. I have the hearing app installed on my phone and have a spare wifi only phone at their house for visitors. I am encouraging my brother and sisters to download the hearing app as well. Thank you for giving my father back some sense of participation in his surroundings

iPhone app 'Note, Listen for Deaf'

by scenicbrook
I am a deaf person and this application is great!! I can hand my phone to anyone, they speak into the phone and it converts the speach to text. I read lips and find it very helpful in restaurants where lip reading is very difficult.

Works great This is great software! It is now possible to speak to a deaf person and let him/her read what you are saying. For the future it would be perfect if this could also be used for remote chat, like Skype or Viber, but for now this enables improved communication between deaf and hearing!

Latest news about Deaf-Hearing Chat development :  twitter.com/Sarslander 

Thank you!

      Thanks a lot to all our buyers! Dozens of users throughout the world. They use different languages, but communicative issues between the deaf and hearing are the same in Russia, USA, Germany, Australia, India, Brazil, UK, Korea and many, many other countries. The finest is that my customers are very clever persons who make their balanced decision having tried the trial version. The most important thing for them is that they receive the new tool for communication. It’s important for them to make barriers lower and remove them at all. My buyers now are looking for making the communication more available. That is really the most valuable thing we have.
     I receive letters from buyers who lost their sense of hearing in adult age. For them, my complex turned out to be the real rescue. These people don’t know gestural language and cannot read by lips. However, they save their desire and need to communicate. Many of them became very alone. What one should do if a wife has lost her hearing sense, but her husband hears. It’s very difficult even simply discuss something. Paper notes or sms—all of them are too inconvenient. My complex allows talking for many hours and looking to each other’s eyes.
     I invented this complex for myself to communicate with my son. When I’d seen that the results were really wonderful, I decided to publish applications for this complex. I was told that I could do nothing; it’s too expensive and difficult for understanding; that paper notes were more familiar. However, I decided to publish these applications at Google Play. If this helped me, why it couldn’t help to others. Each time when somebody is installing my applications, I feel a great pleasure that one more person has found in this complex namely that he/she looks for. If the people would be little closer to one another thanks to my complex, it means that my life in the Earth is not for nothing.
      Of course, it’s my dream to proceed with development of the complex. To make it something more than only hobby. I am sorry that I have no possibility to make video clips of high quality where is possible to show how one could use the complex in different situations. Unfortunately, I have no possibility to take part in thematic exhibitions. It's a great pity that many people who could use my complex simply know nothing about.
      However, I hope that in future many people could know about my complex and it will become one of everyday communication means for deaf persons.
      Again, thank you a lot!
      Your Sarslander.

User review from Google Play (Deaf-Hearing Chat Device-H)

William - 22 July 2012 - LG Optimus One with version 2
Works great.
Excellent app for its intended purpose. My father who is 84 has been deaf for several years. Until I found this app I have been communicating either with paper and pencil or email. I have tried other chat apps but their font size were small and hard to read. This afternoon I spent 2 hours talking with my father. I installed this app (H) on an old phone (android 2.2). I installed the "D" app on my father's tablet (Android 4.0). Using the voice input (voice to text) I would speak into phone and then press send to transmit the resulting text to my Dad's tablet. He found the font size easy to read. Since it uses Bluetooth it is much faster than sms or email. Also the large text input button was much easier for my 85 year old mother to find with her bad eyes. I installed this app on an old non-contract phone . I did not activate the phones and just use my father's WIFI. Internet connectivity is need for voice to text. For areas WIFI is not available 3G or 4G is need for voice to text. I will install the H app on my activated phone in the future. $4 is nothing to be able to take my Dad to dinner and "talk" to him. The developer of this app gave me outstanding customer service.

My dear son Misha and me.

1. My son Misha is 7 years old.

2. When Misha was two he got ill and after the disease he completely lost his hearing.

3. To develop Misha’s abilities we used cards which denoted certain objects or actions.
4. Misha wasn’t interested in the cards, so his vocabulary remained very poor. All his communication with us came down to the simplest gestures.

5. All that changed with a new complex for communication between the deaf and hearing people, consisting of two Android-devices.

6. This complex includes such modern achievements, as:
- speech recognition and translation of voice messages into text;
- possibility to pronounce messages;
- free messaging, by means of Bluetooth;
- fast typing on a virtual keyboard;
- convenient large font.
7. Using this complex we communicate with Misha every day.
8. Misha always carries his phone in a special pocket. We can address Misha at any moment, because every message is followed by vibration.

9. Misha’s progress is really fantastic. He memorizes dozens of new words every month. It’s not bad, you see, for the seven-year-old boy, who is completely deaf.

10. Now Misha is greatly interested in learning words. He opens books and looks for familiar words. He’s proud of every familiar word he found.
11. As if we teach Misha to speak and he really speaks to us with the help of the complex.
12. If there is a deaf child in your family and you care about his intellectual growth and his communication with you, you really ought to have such a complex and not to lose valuable time.
13. If you doubt just try the complex. It’s a real miracle of communication. If at the present moment you don’t have the second Android-device ask your relatives, friends or acquaintances to give it to you for a while, in order to test the complex.
14. The cost of the complex is very low. If the cost is still high for you, you can buy “secondhand” Android-devices in a commission shop or at an auction. The cost of applications is so low, that is available to everyone in any country of the world. Those fantastic opportunities which the complex will give to your child millions of times will cover the expenses.
15. Many people just don’t know that there is such an opportunity for communication. If you are reading this and you know parents of deaf children, share this information with them. Every single day is important for the children’s development!
16. Buying applications for the complex you’re contributing to rehabilitation of the deaf and helping them to adapt to the modern world of hearing people.

The exchange of messages is possible in any language supported by your Android-devices. Such complex can be used in any country. All messages between the devices free of charge.
