![]() Users can then access the scanned text with adaptive technology devices that magnify the computer screen or provide speech or braille output. With some OCR systems, users can convert these files into formats retrievable by commonly used software such as word processors, spreadsheets, and databases. It also uses a feature that applies spell checking techniques similar to those found in word processors.Īll OCR systems create files containing the characters and page layout of the text. The recognition process in the OCR system takes account of the logical structure of the language. Sample of synthesized speech: "Converting hard copy printed material into properly formatted braille documents can be one of the most challenging tasks for individuals." This file is passed to the built-in screen reader, which uses the computer's sound card or dedicated speech synthesizer to speak the text. The OCR software then analyzes the image, recognizes the characters, and converts the information into an electronic file. ![]() ![]() When users place a printed document in the scanner and issue a command to begin the scan, the scanner takes a picture of the printed text and sends it to the computer. With this technology, users can scan printed, but not hand written, text and either have it read back in synthetic speech or save it to their computer as a file that can be accessed later. To use this technology, users require three components: a flatbed scanner, a PC with a compatible sound card, and a specialized OCR software program with speech output. There are three essential elements to these systems: scanning, optical character recognition, often referred to as OCR, and the reading of the text via synthesized speech. Narrator: Optical Character Recognition systems are one of the tools that allow people who are blind or visually impaired to access printed information.
