Customizing the mobile for Blind in android
<p>i have developed some applications for blind which makes them to use basic mobile functionalities like making call, add contact,delete contact. but now i am in dilemma that how the blind  can even unlock the mobile if he is given the android mobile and navigate through the menu to reach the specific application. So does one need to customize the entire OS by making it interactive to the blind user by responding to "Voice commands" (like "unlock mobile" should unlock it) to enable him to use mobile functionalites. </p>

<p>But i have tried some of the voice recognition tutorials,Voice recogntition approach was not accurate. What could be the possible way to customize the mobile for blind and is it possible to access the internals of the OS and customize it, to make it respond to voice commands?
how to code it i am not getting.</p>

<p>please throw some light on this problem. in what way it could be made possible.</p>
