Interaction System with Smart Phones By Speech to Text and Accelerometer?

we all know that Smart phones with touch screen is being very much popular now a days with lots many entertaining applications in it. But in these smart phones there is one drawback that is touch screen. If anybody wants to use particular application they have to click on the small icon of that Application. So in order run any application we have to click small icon which is not at all safe particularly when user is driving. And if user wishes to use any application at the time of driving he/she can lose their concentration and this can lead to an accident. So to avoid this problem this paper proposes the proximity sensor based no-touch mechanism and Speech to Text (STT) system so that user can easily call or message through speech. And if any accident happened it will send message to the emergency. This accident detection is done with the help of accelerometer’s reading. As this is no-touch mechanism, this application can be initiated by waving the hand over the proximity sensor there is no need to touch the screen in order to initiate this application.
