Window Eyes svensk handbok i PDF-format - Icap

synthesizer drivers will be installed so you can easily switch from synthesizer to synthesizer via the
Select Synthesizer option from the File menu at any time.
Window-Eyes is very easy to get along with. By that we mean it works with many voice synthesizers.
Window-Eyes was not written for a specific synthesizer but takes advantage of each synthesizer's
unique features.

Window-Eyes supports a feature called indexing. Indexing basically is a form of two-way
communication between the voice synthesizer and Window-Eyes. This two-way communication allows
Window-Eyes to determine exactly what word the synthesizer is speaking at any particular moment.
Why is this important? If you are using the read to end feature of Window-Eyes and your synthesizer
supports indexing, you will notice when you cancel the read to end with the ESCAPE key, Window-
Eyes routes the application's cursor to the beginning of the line containing the last word you heard. If
your synthesizer does not support indexing, the cursor will be anywhere from a few lines to many lines
below what you last heard. Since Window-Eyes does not know what the synthesizer is speaking, it
can't move the cursor to the last spoken line. Not all synthesizers support indexing. The sections in
this appendix describe each synthesizer in detail including whether it supports indexing or not.
Re-Initializing Synthesizers
If your synthesizer is connected to a serial port, it is possible for a Windows application (or any other
program) to attempt to send information to it instead of to a modem, mouse, or other serial device.
Since the synthesizer or serial port may react unpredictably, it is essential to have a quick, easy way to
put things to right.
When this happens, your synthesizer may begin to speak characters which are not contained in the
text being spoken or may suddenly stop speaking altogether. It may even start speaking at the wrong
pitch or rate. You can re-initialize your synthesizer by doing the following:
CTRL-BACKSLASH to bring up the Voice Control Panel.
Press the letter I.
Window-Eyes will send a string of commands to your synthesizer which includes rate, pitch, tone, and
volume commands, serial port initialization, and the original initialization string sent to the synthesizer
on startup. Finally, it will announce Synthesizer re-initialized. Press ESC to leave the Voice Control
Panel if you wish.
The Redraw hot key (INS-BACKSLASH) will also re-initialize the synthesizer after the screen has been
refreshed.
Re-initializing a synthesizer will also re-initialize an installed and operating Braille display.
Let's talk specifically about each of the synthesizers in turn. Below is a list of each synthesizer and
what is required in order to use it with Window-Eyes. Also, any unique features relating to each
synthesizer will be discussed. If you require any further information relating to your synthesizer, please
refer to your synthesizer's owners manual.
