Otherwise some ambiguities may occur.

(see audio step 12 below).

The text must be flat and clear.

When the camera takes the snapshot of the paper, it is ensured that there is a good lighting condition. This is in contrast when using text to speech. An existing Linux package, tesseract, is what handles OCR. I found it is best to read parts of a document at a time as full pages can be hard to listen to.

You'll have to replace the line in pitextreader.pyCAMERA = "raspistill -cfx 128:128 --awb auto -rot 180 -t 500 -o /tmp/image.jpg"with something like:CAMERA = "fswebcam /tmp/image.jpg"You will have to add options if needed to rotate or improve the image quality.If fswebcam does not work with your camera, then it is likely that the camera requires a special driver for Linux. I used MediaMonkey on a Windows system for editing the titles. Do not include any other type of files such as picture files or text files. Empowering Visually Impaired people through Technology.

There are better options for controlling volume: Some headphones, especially wireless headphones, are equipped with a volume control. When the camera takes the snapshot of the paper, it is ensured that there is a good lighting condition.

instead of putting 20 authors in the parent folder "literature", one could create a parent folder named "authors A to M" and another one "authors N to Z". Update: Short video demo: https://youtu.be/n8-qULZp0Go.

You can browse through the folder and listen to files by using the appropriate keyboard commands as specified in section "The Remote Control", a. Because they are implemented simply as CSS filter properties, they don't apply directly to the canvas image and are not carried over to snapshots.
