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 + +What: /sys/accessibility/speakup/ex_num +KernelVersion: 2.6 +Contact: speakup@linux-speakup.org +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: + +What: /sys/accessibility/speakup/silent +KernelVersion: 2.6 +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/<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. + +What: /sys/accessibility/speakup/<synth-name>/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/<synth-name>/delay_time +KernelVersion: 2.6 +Contact: speakup@linux-speakup.org +Description: TODO: + +What: /sys/accessibility/speakup/<synth-name>/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/<synth-name>/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/<synth-name>/flush_time +KernelVersion: 5.12 +Contact: speakup@linux-speakup.org +Description: Gets or sets the timeout to wait for the synthesizer flush to + complete. This can be used when the cable gets faulty and flush + notifications are getting lost. + +What: /sys/accessibility/speakup/<synth-name>/full_time +KernelVersion: 2.6 +Contact: speakup@linux-speakup.org +Description: TODO: + +What: /sys/accessibility/speakup/<synth-name>/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/<synth-name>/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/<synth-name>/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/<synth-name>/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/<synth-name>/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/<synth-name>/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/<synth-name>/trigger_time +KernelVersion: 2.6 +Contact: speakup@linux-speakup.org +Description: TODO: + +What: /sys/accessibility/speakup/<synth-name>/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/<synth-name>/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. + |
