Text-to-speech converter using optical character recognition - reads scanned text into memory for reproduction by loudspeaker or on video screen at discretion of user

摘要

The text is scanned optically and read by a microprocessor into a digital memory, with conversion of the optical signals into ASCII code by an OCR computer program. The microprocessor is also in a position to render the ASCII encoded test into acoustic output. The scanned text can be also be reproduced on a screen with any desired deg. of enlargement, and scrolled under the control of the reader. USE/ADVANTAGE - By visually handicapped or reluctant readers, text can be understood more rapidly, accurately and economically than with conventional enlarging TV reprodn. equipment.
