Technology is changing the lives; it has not only made the life easier but also assisting the people to overcome their problems. NVDA (Non Visual Desktop Access) is a free and open source software for visually impaired persons that can read on screen text. It reads the text as you move your mouse on the different windows of the screen and type with your keyboard as well. It can recognize more than 35 languages including Indian languages (UNICODE format). NVDA screen reader uses forment synthesis method to output the text as voice. It uses eSpeak synthesizer by default to output the voice and also allows you to select different synthesizer but one must go for eSpeak to read UNICODE text.

We have just learnt how NVDA screen reader assists vision impaired persons. While writing this post I just thought of using Flutter app for blinds which could help them to play or pause their lessons which they listen from media player or VLC. They can just show there hand to laptop’s webcam to pause their lessons and start again by same action. In this way they can interact with laptop or PC (with webcam) without touching a single key. Read our post on Flutter gesture recognition app.
While writing about NVDA screen reader software I must mention Mr. T.S. Shreedhar who has contributed his knowledge to NVDA software to add Indian languages. He is now working with the project to read the content of mobile or tablets.
