DH Chat by sarslander on iPhone!

Deaf  Hearing Chat on  iPhone, iPod, iPad !

Install the “Deaf-Hearing Chat ” application on the first device (which will be used by a deaf person). 
Install the “Deaf-Hearing Chat” application on the second device (which will be used by a hearing person). 
Run the applications on both devices and link the devices via Bluetooth. 
A hearing person speaks into the phone, the application transforms the speech into a text message and sends it to the device used by a deaf person. You can also exchange text messages between the devices. 
The complex is very convenient for regular communication in families with a deaf family member. Each message is followed by vibration (iPhone), so you can always call a deaf person, address him / her. 
The complex may also be used by a deaf person to communicate with hearing people in a shop, a hospital, a bank, etc. In this case, a deaf person should have both devices with him / her and pass a device with a pre-installed “Deaf Hearing Chat” application to a hearing manager or consultant to start communication at any time. 

The application Deaf-Hearing Chat , enables a hearing person to type text messages on a virtual keyboard or using voice input (the button “Voice Input” or the button "Say and Send" ). You need an Internet access for voice input. To send a message to second device you should press the button “Send”. The messages, received from the second device, are shown on the display.

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.

      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.
