Speech to text and accelerometer based smart phone interaction system

Smart phones with touch screen have become very popular and it has changed the behaviour of using handsets as many applications and features are inbuilt into it. But this smart phones are not safe to handle at the time of driving as the user have to touch the small icons of the screen and while doing that he may lose the concentration which increase the accident risk. So to avoid this problem this paper proposes the no-touch mechanism with the help of proximity sensor and Text to Speech and speech to text systems. And just in case any accident happens it will drop the message to the emergency number. As there is no touch mechanism we can initiate the applications without touching the screen by just waving the hand on proximity sensor twice. Text to Speech (TTS) and Speech to Text (STT) Systems are used for notification of the incoming messages through the voice and if user wishes to call to the particular contact in his contact list he can just call the name of that person and the call will get connected.
