1. VOICE BASED EMAIL FOR BLINDS

2. INTRODUCTION
 Dictation
using speech recognition could
potentially serve as an efficient input method
for mailing devices for blind.
 However,
dictation systems follows a speech
interaction model

3.  We
introduce Voice Typing, a new speech
interaction model where blinds, utterances are
transcribed as they produce them to enable
real-time error identification
 Voice
Typing aspires to create an experience to
having a secure type for you, while you monitor.

4. DESIGN AND IMPLEMENTATION
 This
project is designed using some set of
APIs.
 SNMTP(Simple
Network Mail Transmission
Protocol) has been used for mailing
servicing.
 Voice
Typing and Dictation Speech
Interaction Models are designed using the
Windows 7 LVCSR dictation engine.

5.  In
order to control speech accuracy, we
turned off the (default) MLLR acoustic
adaptation.
 Error
Correction Methods are
implemented using the Windows 7 API’s
and Windows Presentation Foundation
(WPF).

10. EXISTING SYSTEMS AND PROBLEMS
 Outdoor communication is becoming a harder task for
blind and visually impaired people in the
complex urban world.
 Advances in technology are causing the blind to fall
behind, sometimes even putting their lives at risk

314 million visually impaired people in the world today

45 million blind are there.
