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 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.
