OCR and Speech

OCR and Speech Quick Start

To quickly capture and process a document, do the following:

1. Tap the screen once in the bottom right corner to start OCR mode.

The screen goes dark for a moment as TOPAZ switches from the video
magnification camera to the OCR camera.

Note:

To switch to OCR mode, the default method is to tap the screen in the

lower right corner. This can be changed so that any tap on the screen
while in video magnifier mode will automatically launch OCR mode. For
more information, refer to

Activate Speech (Starting OCR Mode)

on

page 55.

2. When "Speech on" is announced, position the document so that it displays

inside the yellow document outline box that appears on the screen.
