Also<br> look at Perlbox [2]. (Note that neither Gnome Do or Perlbox can be used<br> directly.)<br> - integrate with GnomeVoiceControl [3], which already uses PocketSphinx<br> and should be highly compatible with Sugar. This could allow voice<br> control of unmodified Activities.<br> <br></blockquote><div>I have already gone through Gnome Voice control which I think is the best option for integrating into sugar. The reason being it uses Pocket Sphinx which is light weight and thus should be compatible with devices like XO-1.0. The run time memory requirements of Pocket Sphinx are upto 20 MB. </div> <div>During next few days, I will be testing the functionality of Pocket Sphinx in sugar and familiarizing myself more with Gnome voice control. </div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"> Speech Recognition:<br> - supply text to any unmodified activity<br> - control input language easily for multilingual users<br> <br> [1] <a href="http://do.davebsd.com/index.shtml" target="_blank">http://do.davebsd.com/index.shtml</a><br> [2] <a href="http://perlbox.sourceforge.net/" target="_blank">http://perlbox.sourceforge.net/</a><br> [3] <a href="http://live.gnome.org/GnomeVoiceControl" target="_blank">http://live.gnome.org/GnomeVoiceControl</a><br> <br> </blockquote></div><div>I have broken the proposal into following parts that should be done in sequence:</div><div><br></div>a) My first priority this summer is to enable "Sugar Voice Control".

A command line interface that will start speech recognition in the background and will start taking "Speech Commands".</div> <div> </div><div>b) After the successful implementation of Sugar Voice control, we can then look into providing speech recognized text to unmodified sugar activities. Thus activities like Write can be made to get the required inputs either from Keyboard or through microphone. This includes:</div> <div><br></div><div>1. P<span class="Apple-style-span" style="font-family: Arial, sans-serif; font-size: 13px; line-height: 19px; ">roviding a Speech recognition button in the sugar frame (for example on Top Right hand side) which when clicked will automatically start recognizing speech in the background. Clicking the same button again will stop the recognition process. </span></div> <div><span class="Apple-style-span" style="font-family: Arial, sans-serif; font-size: 13px; line-height: 19px; "><br></span></div><div><span class="Apple-style-span" style="font-family: Arial, sans-serif; font-size: 13px; line-height: 19px; ">2.
