NAME

       screader - Screen reader using a software Text-To-Speech package or a hardware speech synthesizer.

SYNOPSIS

       screader [`screen' options]

DESCRIPTION

       The screader background program reads the screen and puts the information through to a software Text-To-Speech package (Like `festival') or
       a hardware speech synthesizer. (like `Accent') It uses the device /dev/vcsa. (See below)

       A reverse space at column 80 indicates the line containing the internal pointer.

SCREADER KEYS

       The following TTS-commands are available: (Each command must be pressed with the left-ALT-key, unless screader is in direct mode.  See  the
       `z'-command.)

       a      Toggles  auto_speak  on  or off. When toggled on screader will speak out the character being typed or the typed word if word_mode is
	      toggled on.

       b      Put internal pointer to begin of current line and speaks that line out if line_speak is toggled on.

       c      Screader speaks out the line containing the cursor.

       d      Puts the internal pointer one line down.	If line_speak is on screader speaks out that line.

       e      Speak out character or word under the cursor.

       f      Toggle for the internal pointer to follow the cursor or not.

       g      Puts the internal pointer to the bottom of the screen.  If line_speak is on screader speaks that line out.

       h      Puts the internal pointer to the top of the screen.  If line_speak is on screader speaks that line out.

       i      Toggles line_speak on or off. When toggled on screader will speak out the line, which is pointed to by the internal  pointer,  every
	      time it has changed.

       k      Toggles key clicking on or off. When toggled on screader will give a short click after a key is pressed.

       ,      Puts the pointer left one word. If auto_speak is toggled on screader speaks out that word.

       l      Puts  the  internal  pointer  one  character left. If auto_speak is on, screader speaks out the character pointed to by the internal
	      pointer.

       m      Toggles the word_mode on or off. When toggled on screader speaks out words instead of characters.

       n      Toggle for numbers. If toggled on (default) screader speaks out the value of the digits.	Otherwise screader  speaks  out  digit	by
	      digit.  If in word_mode, words will be spelled.

       o      Silence please.

       p      Speaks out character or word pointed to by the pointer.

       q      Toggles punctuation on or off.  When toggled on screader will put each punctuation mark through to a  script punctuation.N.sh.  Oth-
	      erwise screader will replace each punctuation mark by a space, so  that  only  alphabetic characters and digits  are  spoken.   (See
	      PUNCTUATION SCRIPT.)

       .      Puts the pointer right one word. If auto_speak is toggled on screader speaks out that word.

       r      Puts  the  internal  pointer  one character right. If auto_speak is on, screader speaks out the character pointed to by the internal
	      pointer.

       s      Screader speaks out the line pointed to by the internal pointer.

       u      Puts the internal pointer one line up.  If line_speak is on screader speaks out that line.

       w      Speaks out the whole screen.

       x      Re-read the `tts' file. (if another TTS is desired.)  Each time this combination is pressed screader will select the  next  TTS-com-
	      mand from this file. (if any, else the first one will be selected. and so on)

       z      Put  screader  in  direct  mode. In this mode each command can be given without the alt-key, so that reviewing the screen is easier.
	      When the `z'-key is pressed, screader goes back to application mode, so that you can work with your application again.

       -      Toggles repeat_mode on or off. If toggled on, every sequence of the same characters will be spoken as `character n times`.  where  n
	      stands for the number of that character in the sequence.

       '      Toggles caps_mode on or off. If toggled on screader speaks the word `cap' before each capitalized character.

       =      Makes the internal pointer equal to the cursor.

SCREEN_DEVICE
       Screader reads its information from a device /dev/vcsa. Kernels 1.1.92 or later provide this device.

PUNCTUATION SCRIPT

       Each  time  screader  encounters a punctuation mark, it will be put through to a script called punctuation.N.sh, where N corresponds to the
       Nth tts-command in the tts-file. If there is no punctuation script the punctuation mark will be directly put through to	the  current  tts-
       command.

FESTIVAL CLIENT

       If you want to use the server/client option of Festival place the line:

	      festival_client.sh

       as  first  command  in the file /etc/screader/tts.  It is supposed that before using this tts-command the festival server is started by the
       following command:

	      festival --server &

BUGS

       When typing fast sometimes the whole line will be spoken out instead of the characters being typed when line_speak and auto_speak are  tog-
       gled on.  Also when word_mode is toggled on the whole line will be spoken out when typing.
