input by people unable to use a keyboard and by those using mobile devices.
 Open Mind Speech: GPL based speech recognition tools and application.
It is intended to collect speech data from "e-citizens" using the Internet.
 Dspeech: TTS (Text To Speech) program with functionality of integrated
ASR (Automatic Speech Recognition). It is able to read aloud the written
text and choose the sentences to be pronounced based upon the vocal
answers of the user. Allows you to save the output as a .WAV or .MP3 file
and allows quick select icon of different voices, even combine them, or

Recommendations
• Ramification and implication of sustainable policy for PwD’s;
• Availability of documents in various forms like text, audio,
video and also in Braille including Daisy and EPUB supported
formats .
• Identification of right assistive technologies for the right
persons.
