+What: /sys/accessibility/speakup/attrib_bleep
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: Beeps the PC speaker when there is an attribute change such as
+ foreground or background color when using speakup review
+ commands. One = on, zero = off.
+
+What: /sys/accessibility/speakup/bell_pos
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: This works much like a typewriter bell. If for example 72 is
+ echoed to bell_pos, it will beep the PC speaker when typing on
+ a line past character 72.
+
+What: /sys/accessibility/speakup/bleeps
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: This controls whether one hears beeps through the PC speaker
+ when using speakup's review commands.
+ TODO: what values does it accept?
+
+What: /sys/accessibility/speakup/bleep_time
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: This controls the duration of the PC speaker beeps speakup
+ produces.
+ TODO: What are the units? Jiffies?
+
+What: /sys/accessibility/speakup/cursor_time
+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
+ and better synchronisation between cursor position and speech.
+
+What: /sys/accessibility/speakup/delimiters
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: Delimit a word from speakup.
+ TODO: add more info

+Description: TODO:
+
+What: /sys/accessibility/speakup/key_echo
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: Controls if speakup speaks keys when they are typed. One = on,
+ zero = off or don't echo keys.
+
+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
+ format. A special program called genmap is needed to compile a
+ textual keymap into the binary format which is then loaded into
+ /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
+ it finishes.
+
+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
+ punc_level is set to four.
+
+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
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: This is a list of all the punctuation speakup should speak when
+ punc_level is set to two.
+
+What: /sys/accessibility/speakup/punc_some
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: This is a list of all the punctuation speakup should speak when
+ punc_level is set to one.
+
+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
+ keys are pressed. If say_control is set to zero, shift, ctrl,
+ and alt are not spoken when they are pressed.
+
+What: /sys/accessibility/speakup/say_word_ctl
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: TODO:

+Contact: speakup@linux-speakup.org
+Description: TODO:
+
+What: /sys/accessibility/speakup/spell_delay
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: This controls how fast a word is spelled
+ when speakup's say word
+ review command is pressed twice quickly to speak the current
+ word being reviewed. Zero just speaks the letters one after
+ another, while values one through four
+ seem to introduce more of
+ a pause between the spelling of each letter by speakup.
+
+What: /sys/accessibility/speakup/synth
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: Gets or sets the synthesizer driver currently in use. Reading
+ synth returns the synthesizer driver currently in use. Writing
+ synth switches to the given synthesizer driver, provided it is
+ either built into the kernel, or already loaded as a module.
+
+What: /sys/accessibility/speakup/synth_direct
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: Sends whatever is written to synth_direct
+ directly to the speech synthesizer in use, bypassing speakup.
+ This could be used to make the synthesizer speak
+ a string, or to
+ send control sequences to the synthesizer to change how the
+ synthesizer behaves.
+
+What: /sys/accessibility/speakup/version
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: Reading version returns the version of speakup, and the version
+ of the synthesizer driver currently in use.
+
+What: /sys/accessibility/speakup/i18n/announcements
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: This file contains various general announcements, most of which
+ cannot be categorized. You will find messages such as "You
+ killed Speakup", "I'm alive", "leaving help", "parked",
+ "unparked", and others. You will also find the names of the
+ screen edges and cursor tracking modes here.
+
+What: /sys/accessibility/speakup/i18n/chartab
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: TODO
+
+What: /sys/accessibility/speakup/i18n/ctl_keys
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: Here, you will find names of control keys. These are used with
+ Speakup's say_control feature.
+
+What: /sys/accessibility/speakup/i18n/function_names
+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
+ how Speakup pronounces a given character. You could, for
+ 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
+ Characters' in Speakup User's Guide (file spkguide.txt in
+ source).
+
+What: /sys/accessibility/speakup/i18n/colors
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: When you use the "say attributes" function, Speakup says the
+ name of the foreground and background colors. These names come
+ from the i18n/colors file.
+
+What: /sys/accessibility/speakup/i18n/formatted
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: This group of messages contains embedded formatting codes, to
+ specify the type and width of displayed data. If you change
+ these, you must preserve all of the formatting codes, and they
+ must appear in the order used by the default messages.
+
+What: /sys/accessibility/speakup/i18n/key_names
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: Again, key_names is used by Speakup's help system. In the
+ previous example, Speakup said that you pressed "keypad 3."
+ This name came from the key_names file.
+
+What: /sys/accessibility/speakup/<synth-name>/
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+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
+ speaking uppercase letters. In the case of the soft synthesizer
+ and most others, this returns the pitch of the voice
+ down to the
+ currently set pitch.
+
+What: /sys/accessibility/speakup/soft/delay_time
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: TODO:
+
+What: /sys/accessibility/speakup/soft/direct
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: Controls if punctuation is spoken by speakup, or by the
+ synthesizer.
+
+ 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
+Contact: speakup@linux-speakup.org
+Description: Gets or sets the frequency of the speech synthesizer. Range is
+ 0-9.
+
+What: /sys/accessibility/speakup/soft/full_time
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: TODO:
+
+What: /sys/accessibility/speakup/soft/jiffy_delta
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: This controls how many jiffys the kernel gives to the
+ synthesizer. Setting this too high can make a system unstable,
+ or even crash it.
+
+What: /sys/accessibility/speakup/soft/pitch
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: Gets or sets the pitch of the synthesizer. The range is 0-9.
+
+What: /sys/accessibility/speakup/soft/inflection
+KernelVersion: 5.8
+Contact: speakup@linux-speakup.org
+Description: Gets or sets the inflection of the synthesizer, i.e. the pitch
+ range. The range is 0-9.
+
+What: /sys/accessibility/speakup/soft/punct
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: Gets or sets the amount of punctuation spoken by the
+ synthesizer. The range for the soft driver seems to be 0-2.
+ TODO: How is this related to speakup's punc_level, or
+ reading_punc.
+
+What: /sys/accessibility/speakup/soft/rate
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: Gets or sets the rate of the synthesizer. Range is from zero
+ slowest, to nine fastest.
+
+What: /sys/accessibility/speakup/soft/tone
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: Gets or sets the tone of the speech synthesizer. The range for
+ the soft driver seems to be 0-2. This seems to make no
+ difference if using espeak and the espeakup connector.
+ TODO: does espeakup support different tonalities?
+
+What: /sys/accessibility/speakup/soft/trigger_time
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: TODO:
+
+What: /sys/accessibility/speakup/soft/voice
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: Gets or sets the voice used by the synthesizer if the
+ synthesizer can speak in more than one voice. The range for the
+ soft driver is 0-7. Note that while espeak supports multiple
+ voices, this parameter will not set the voice when the espeakup
+ connector is used between speakup and espeak.
+
+What: /sys/accessibility/speakup/soft/vol
+KernelVersion: 2.6
+Contact: speakup@linux-speakup.org
+Description: Gets or sets the volume of the speech synthesizer. Range is 0-9,
+ with zero being the softest, and nine being the loudest.
