VOICE BASED EMAIL FOR BLINDS

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

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.

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.

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).

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.
