The document discusses a voice-based email system designed for blind users, utilizing a new speech interaction model called voice typing for real-time error identification. It highlights the technology's implementation, hardware and software requirements, and the challenges faced by visually impaired individuals in communication. Key issues addressed include accessibility, technology reliance, and the need for a cost-effective and user-friendly solution.

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.
