+What:		/sys/accessibility/speakup/keymap
+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+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

+What:		/sys/accessibility/speakup/punc_all
+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+Description:	This is a list of all the punctuation speakup should speak when

+
+What:		/sys/accessibility/speakup/punc_level
+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+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.
+
+What:		/sys/accessibility/speakup/punc_most

+
+What:		/sys/accessibility/speakup/reading_punc
+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.
+
+What:		/sys/accessibility/speakup/say_control
+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+Description:	If set to one, speakup speaks shift, alt and control when those

+
+What:		/sys/accessibility/speakup/synth
+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+Description:	Gets or sets the synthesizer driver currently in use. Reading

+
+What:		/sys/accessibility/speakup/synth_direct
+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+Description:	Sends whatever is written to synth_direct

+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+Description:	Here, you will find a list of names for Speakup functions.
+		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.
+
+What:		/sys/accessibility/speakup/i18n/states
+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+Description:	This file contains names for key states.
+		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.
+
+What:		/sys/accessibility/speakup/i18n/characters
+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+Description:	Through this sys entry, Speakup gives you the ability to change

+		example, change how some punctuation characters are spoken. You
+		can even change how Speakup will pronounce certain letters. For
+		further details see '12.  Changing the Pronunciation of

+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/soft/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.
+
+What:		/sys/accessibility/speakup/soft/caps_stop
+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+Description:	This is the string sent to the synthesizer to cause it to stop

+		down to the
+		currently set pitch.

+Description:	Controls if punctuation is spoken by speakup, or by the

+		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.
+
+What:		/sys/accessibility/speakup/soft/freq
+KernelVersion:	2.6

+KernelVersion:	2.6
+Contact:	speakup@linux-speakup.org
+Description:	Gets or sets the voice used by the synthesizer if the
