In this paper we introduce Voice Control Device (VCD), which provides non-visual access to the Android Operating System. It offers many contributions in the application. Firstly, it enables system wide Voice Control and can accommodate any application. Secondly, it can construct many commands which the user can easily use, and lastly it is very efficient and natural way of interaction with the user which provide many features. The two main features used in this application are Text-To-Speech which converts digital data or text in the form of speech and Speech-To-Text which converts speech in the form of text or digital data which the application can process internally. These features are very helpful for visually impaired people. Using these features user can access other functions of the application like Current Location, Navigation, Assistant, Calling Guardian, Texting, Google Map features etc. The main function which user can use is that they can listen to the surrounding so that they can visualize the scene in their mind and travel on road by getting the analyzed data from the smart cane connected to the phone.
