Ja Medlicott

• “Text-to-Speech software is used to convert words from a computer document (e.g. word processor document, web page) into audible speech spoken through the computer speaker”
Reasons for Using a Text Reader
• Visual Issue
(Difficulty seeing text)
• Cognitive Issue
( Low reading level/comprehension)

How to get Printed Text into your Computer
Scan
A scanner takes a picture of the document
A scanned document is a picture first!
Example Scan Text.jpg
Can a text reader read a picture?
It can not!
Must have additional software to change or format it into a text file or document
This software is called
OCR
Optical Character Recognition
Optical Character Recognition (OCR)
Converts the scan picture of text into a true text file or document.
Most scanners you buy today come with their own OCR software

Cutting a book …damages it and page order is a issue
