This document presents a voice operated web browser called Smowser. Smowser uses Microsoft Speech SDK for voice control integration to allow users to operate a web browser using voice commands. The voice commands are converted to text and matched to a set of predefined commands to execute browser functions like opening bookmarks, refreshing pages, scrolling, and tab operations. The presentation concludes that voice-based browsers allow for more interactive browsing and that greater accuracy is still needed for speech recognition, especially for accent recognition.

3. Objective
 To develop a Web Browser which can be operated using
Voice Commands.
 Integrated functioning rather than plug-in dependency.
 Combined auditory and visual input.
 Offline feature independent of connection state.

4. Introduction
 Human-computer interaction is more advantageous than
conventional browsing.
 Control browser over distance, in the dark and while
hands are occupied.
 Useful to people with disabilities and vision problems.

5. Literature Review
 Voice Portal
 VoiceXML
 Third party plug-ins and add ons.
 Microsoft Speech Application Programming Interface
(SAPI)

6. Problem Definition
 Connectivity required by Microsoft Cortana.
 Google Chrome & Mozilla Firefox requires add ons.
 Voice Portals are limited to websites.
 CMU Sphinx supports only Linux.

7. Proposed Solution
 The Smowser will be using Microsoft Visual Studio for
developing the web browser using Dot NET framework with
C# programming language.
 It will be using Microsoft Speech SDK for voice control
integration.
 Voice commands are converted into text and then matched
with a set of pre-stored commands and execute them.
