OCR

OCR (optical character recognition) is technology that converts pictures of text - such as scanned pages - into real, machine-readable text that can be selected, searched, and read aloud by a screen reader.

Most PDF tools include an OCR feature for turning scanned documents into accessible ones, though the recognized text should be proofread for errors: OCR can misread unusual fonts, low-quality scans, or non-Latin scripts, and those errors get read aloud exactly as recognized.
