2. Vision Statement
Voice Browsers offer the promise of allowing everyone to access Web based services from any phone, making it practical to access the Web any time and any where, whether at home, on the move, or at work.
Thus Application development has to be designed not only with web as a focus but should be able to span all kinds of devices.
Also Multilingual access to data will enable reaching to more number of people
