2. Visual Language
Visual Language

• Multimedia communication tool for the cerebral palsy affected.

• This project examines new methods of representing the meaning of words and sentences using visual representations to the specially challenged.

• The initial goal is to design an interlingua (a language independent representation of meaning) for limited domain communication.

• This research has been applied to develop a  communication tool that provides the disabled with an ability to communicate.
3. Sanyog™:(Indian Language based Communication Tool for children with Cerebral Palsy)
Sanyog is a multilingual Augmentative & Alternative Communication system, developed at Media Lab Asia research hub at IIT Kharagpur, to serve individuals with speech impairment and neuro-motor disorders. It allows individuals to form and vocalize their own messages. The system is comprised of a Natural Language Sentence Generator, Icon Interpretation and Disambiguation, Text-to-Speech System, a predictive virtual keyboard, facility to store and retrieve frequently used messages, and varied access switches. At present, the system supports three languages, namely Bengali, Hindi and English. The system has been deployed at IICP, Kolkata; AADI, New Delhi; NIMH, Hyderabad and Manovikas Kendra, Kolkatta, where it is being used by a number of students with special needs, facilitating improved communication with teachers and parents. A multilingual communication system with particular application to needs of the children with neuro-motor disorders has been acclaimed by the Engineering Society of Detroit, Michigan and The National Multiple Sclerosis Society, Michigan Chapter, USA by “DA Vinci” Award. Phase-II of Sanyog is in pipeline. The aim in this phase is to develop embedded version of Verb Directed Sanyog as well as enhancement of Desktop version. This includes - Object Directed iconic interface, Generation of sentences from Phrasal Icons instead of Word level icons and Study of multi-sentence text generation with icons.

Sanyog-II, an AAC (Augmentative and Alternative Communication) system for children with cerebral palsy, has been test deployed at AADI (Action for Ability, Development and Inclusion) School, New Delhi.

4. Shruti: (Vernacular Speech Interface for People with visual Impairment)

Shruti has been developed at Media Lab Asia research hub at IIT Kharagpur. It is an embedded Indian language Text-to-Speech system that accepts text inputs in two Indian languages - Hindi and Bengali, and produces near natural speech output. Facility has also been provided to enter the text in ITRANS, using which the Indian language text can be entered using Roman characters. The system has been ported to popular Windows based PDAs. Shruti provides a speech based communication interface for a large number of Indians suffering from speech impairments and forms an integral part of a talking web browser for the visually challenged. Shruti has been deployed at following locations for field trial - IICP, Kolkatta; AADI, New Delhi; Monovikas Kendra, Kolkatta; NIMH, Hyderabad, IIT, Delhi for integration with file reader software, NAB, Delhi for integration with SAFA. Now Phase II of the project has been taken up aiming development of Vernacular Speech Recognition system. The purpose is to develop a Continuous, speaker independent speech recognizer for Hindi and Bangla and an open corpus of tagged speech data. Speech recognition system will consist of following parts –
-Word Boundary Detection
-Feature Extraction
-Pattern Learning
-Language Modeling

In phase-II, emphasis is on developing a data corpus by collecting data in different environments.


5. Screen Reading Software - SAFA (Screen Access for All)

From the day of dawn of the computer technology, it has affected the lives of millions of people, including the lives of visually challenged persons. Advances in synthetic speech have lead to the development of screen reader software, which can capture text from the computer and transform it into the audio form, which is then used by the visually impaired persons or person with low vision.

This technology has provided innumerous opportunities to the visually impaired persons including the jobs as programmers, call centers, venturing in to new fields such as science & math, and others.
Although screen-reading technology has provided such a power to the visually impaired persons, it has hardly reached to the broader population in India & has remained limited to a small fortunate English-speaking minority.

The major issue with this category of assistive technology is that most products are extremely expensive and are beyond the reach of visually impaired persons at least in developing countries.

Media Lab Asia & NAB Delhi have jointly developed the screen reading software named SAFA. This is an open source software & supports many Indian languages. It is being provided free of charge by NAB Delhi. The users have the option of purchasing additional Text To Speech (TTS) softwares for better synthetic voice output from SAFA.

SAFA can detect the text language on the fly and calls the relevant TTS for speaking it. So now one can have a multilingual document and read it with SAFA at one go without having to change or install TTS again & again. The latest version of SAFA is supporting the following TTS in different Indian languages -
-    eSpeak – English, Hindi, Tamil
-    Shruti – Hindi, Bangla
-    VAACHAK – English, Hindi, Marathi
-    Ashrir – Bangla, Marathi, Tamil, Telugu

To add to this list, the developers have made it very easy to add any new language in SAFA whether Indian or foreign. As & when SAPI 5 compliant TTS becomes available for any new language such as Sinhala, all that will be required to do is some changes in the SAFA configuration file and after that SAFA will start supporting that language with speech. This kind of configuration can be done by the user itself. SAFA is being developed & refined continuously as per the features wish list & feedback received from users.
Increasing User’s Base

After the official launch of SAFA (Screen Access for All) on 12th March 2008 at India International Center, the Query about this software has suddenly increased on Helpline. We are receiving around 25 calls weekly about this software which contains
  • Information about SAFA
  • Compatibility of SAFA with third Party software
  • Trouble shooting of SAFA
  • Help for learning  SAFA like short term training programmes

All these show that the user’s base of SAFA is increasing day by day. Apart from this the Name of SAFA is also available in Wikipedia page. The address of Wiki page is -


Feedback from the users shows SAFA is better as compared to JAWS for Hindi

The user comments for SAFA are extremely encouraging. Many users who are using SAFA in there Office for daily work like Hindi typing and other routine work, they are saying that this software has given them new life and motivation of working in office environment where they can enjoy work and as well as the company of there office co-workers. The school and college going students are also happy as now they can type Hindi assignments and papers as per there knowledge and they don’t need to depend on other for complete these important work.

The comparison between SAFA and Jaws for Hindi can be understood from table given below

Screen Access for All
Jaws for Hindi
Keyboard Layout
While using SAFA user can type in three different keyboard layouts like inscripts phonetic and godrej typewriter. And beauty of these layout that these has been added in system level so user can use these keyboard layout in any application In jaws for hindi, user can use only inscript  keyboard layout. Jaws does not support other typing styles.
The major feature of SAFA is that user can use different TTS for different language.
In jaws user has to work only in one TTS
Auto detection of Language
SAFA can identify the different language automatically and call the relative TTS to pronounce the word other vice it will announce “unsupported Character”
In jaws user don’t have any option to identification of different language
Pronunciation of Joint characters and wobbles
Safa has no issue in this regard 
Jaws is not able to read those words properly which are having joint characters and some special wobbles.
This software is available at free of cost from NAB website.
This software is available in demo from Freedom scientific website. To obtain a jaws which support hindi, one has to purchase this software from dealer
Adding new TTS language
It is very easy to add additional languages and TTS in SAFA
You may not be able  to add new language which are not supported by jaws

According to this comparison one can automatically identify the importance of SAFA in user point of view
