In case the serial port or cable got faulty, we may not be getting acknowledgements any more. The driver then currently waits for 4s to avoid jamming the device. This makes this delay configurable.

Description: Beeps the PC speaker when there is an attribute change such as

foreground or background color when using speakup review

KernelVersion: 2.6
|

Contact: speakup@linux-speakup.org
|
|
Description: This controls cursor delay when using arrow keys. When a
|
|
connection is very slow, with the default setting, when moving
|
|
with the arrows, or backspacing etc. speakup says the incorrect
|
|
characters. Set this to a higher value to adjust for the delay

|
|
Description: Speakup keymap remaps keys to Speakup functions.
|
|
It uses a binary

/sys/accessibility/speakup/keymap.

What: /sys/accessibility/speakup/no_interrupt

KernelVersion: 2.6

Contact: speakup@linux-speakup.org
|
|
Description: Controls if typing interrupts output from speakup. With
|
|
no_interrupt set to zero, typing on the keyboard will interrupt
|
|
speakup if for example
|
|
the say screen command is used before the
|

entire screen is read.
|
|
|
|
With no_interrupt set to one, if the say

screen command is used, and one then types on the keyboard,

speakup will continue to say the whole screen regardless until

KernelVersion: 2.6

|
|
Description: Controls the level of punctuation spoken as the screen is
|
|
displayed, not reviewed. Levels range from zero no punctuation,
|
|
to four, all punctuation. One corresponds to punc_some, two
|
|
corresponds to punc_most, and three as well as four both
|
|
correspond to punc_all. Some hardware synthesizers may have
|
|
different levels each corresponding to three and four for
|
|
punc_level. Also note that if punc_level is set to zero, and
|
|
key_echo is set to one, typed punctuation is still spoken as it
|
|
is typed.

KernelVersion: 2.6
|
|
Contact: speakup@linux-speakup.org
|
|
Description: Almost the same as punc_level, the differences being that
|
|
reading_punc controls the level of punctuation when reviewing
|
|
the screen with speakup's screen review commands. The other
|
|
difference is that reading_punc set to three speaks punc_all,
|
|
and reading_punc set to four speaks all punctuation, including
|
|
spaces.

What: /sys/accessibility/speakup/repeats
|

KernelVersion: 2.6

|
Contact: speakup@linux-speakup.org
|
|
Description: A list of characters speakup repeats. Normally, when there are
|
|
more than three characters in a row, speakup
|
|
just reads three of
|
|
those characters. For example, "......" would be read as dot,
|
|
dot, dot. If a . is added to the list of characters in repeats,
|
|
"......" would be read as dot, dot, dot, times six.

Description: This controls how fast a word is spelled

review command is pressed twice quickly to speak the current

word being reviewed. Zero just speaks the letters one after

These are used by the help system. For example, suppose that
|
|
you have activated help mode, and you pressed
|
|
keypad 3. Speakup
|
|
says: "keypad 3 is character, say next."
|
|
The message "character, say next" names a Speakup function, and

it comes from this function_names file.

Again, these are part of the help system. For instance, if you
|
|
had pressed speakup + keypad 3, you would hear:
|
|
"speakup keypad 3 is go to bottom edge."
|
|
|
|
The speakup key is depressed, so the name of the key state is
|
|
speakup.
|

This part of the message comes from the states collection.

|
|
Description: In `/sys/accessibility/speakup` is a directory corresponding to
|
|
the synthesizer driver currently in use (E.G) `soft` for the
|
|
soft driver. This directory contains files which control the
|
|
speech synthesizer itself,
|
|
as opposed to controlling the speakup
|
|
screen reader. The parameters in this directory have the same
|
|
names and functions across all
|
|
supported synthesizers. The range
|
|
of values for freq, pitch, rate, and vol is the same for all
|
|
supported synthesizers, with the given range being internally
|
|
mapped by the driver to more or less fit the range of values
|
|
supported for a given parameter by the individual synthesizer.
|
|
Below is a description of values and parameters for soft

synthesizer, which is currently the most commonly used.

What: /sys/accessibility/speakup/<synth-name>/caps_start

KernelVersion: 2.6
|
|
Contact: speakup@linux-speakup.org
|
|
Description: This is the string that is sent to the synthesizer to cause it
|
|
to start speaking uppercase letters. For the soft synthesizer
|
|
and most others, this causes the pitch of the voice to rise
|
|
above the currently set pitch.

|
|
|
For example, speakup speaks ">" as "greater", while
|
|
the espeak synthesizer used by the soft driver speaks "greater
|

than". Zero lets speakup speak the punctuation. One lets the

synthesizer itself speak punctuation.
