Once the note appears properly in camera then image is auto captured and results will be spoken out by Text To Speech engine on android. This app was one of my first project in Freelance that I have developed in my career so the coding styling and logics are very poor but you can have an Idea about it. I used OCR to detect texts on currency note and compared with the data simply to achieve this. Technologies Used Java Android Studio OCR Download Source Code from Github.
