Hi am Shivani I would like to get details on voice based web browser source code in java.

Introduction
This article describes an ActiveX control that can be embedded in an html web page to provide a voice-activated menu tree.

To compile the code you will need VC6, Microsoft's Speech SDK 5.1 and the Internet Explorer headers. (If you have WINXP you may already have the required files on board)

The Demo Program
The demo for this package is a simple web page with two <iframe> elements: the first <iframe> embeds the ActiveX control while the second displays the page contents.

After compiling and registering WebVoiceCtl.dll, look for a folder called demo and double click on the file inside called WebVoice.html. You should see the tree control in the left frame, shown above. Press the Voice button and be patient while the large speech engines are loaded.

Once loaded, you can speak "go to class one" to start the navigation. The control should respond with "Please confirm class one" to which you may reply "positive". The requested item should then be displayed in the right frame.

Speak "help" at any time to get a list of the active commands. If you've just navigated to a page, the help response will be "[scroll] up, down, top bottom; go back or navigate". Speak your scroll commands then say: "navigate" to return to navigation mode.

Hint: turn the volume on your speakers down to avoid feedback into the microphone.

Background
The code attached to this article demonstrates the following technology:

ATL, ActiveX (and wide character string manipulation)
Tree view searching, expanding and collapsing
Owner drawn buttons, edit controls and static controls
Image lists, overlays (and painting inside an ATL composite control)
Using Microsoft's MSXML parser to load and manipulate an XML file
Using C++ to interface with the web browser and the html page
SAPI 5.1, speech recognition and text to speech engines and Visemes
Of course you don't have to understand all of the items above to use this control in your projects but you may find some of the solutions (a couple of which credit other Code Project articles) interesting.
