1 ====== Accessibility ======
3 ===== About =====
5 SliTaz aims to provide some Assistive Technology (AT) tools.
7 ===== Screen magnifier =====
9 SliTaz supplies a screen magnifier whose edges can be resized and that can magnify up to 16x.
10 It also provides graphical tools that enable a crosshair, pixel positions and RGB values. It
11 can be found in the Menu -> Utilities:
13 <code> # tazpkg get-install magnifier
14 </code>
16 ===== Espeak - Text to speech (TTS) =====
18 The espeak speech synthesizer run from the command line can speak text from an input file or
19 from stdin and supports many languages. Espeak can adjust the amplitude, pitch, word gap,
20 speed, etc. It can also write its output to a wave file rather than speaking it directly.
21 Type ''%%espeak --help%%'' for a full list of available options:
23 <code> # tazpkg get-install espeak
24 </code>
26 Example of use:
28 <code> $ espeak -f example.txt
29 </code>
31 ===== On-screen keyboard =====
33 Virtual keyboard (xvkbd) can be used to enter characters into the software of your choice.
34 The menu can be used to change the keyboard layout, function keys, etc. It supports word
35 completion, the removal of unwanted keys and can connect to a remote display. The
36 configuration can be found in the ~/.Xdefaults file:
38 <code> # tazpkg get-install xvkbd
39 </code>
41 ===== Yasr - Screen Reader =====
43 Yasr is a console (text-based) screen reader that operates through the speech-dispatcher
44 interface and espeak:
46 <code> # tazpkg get-install yasr
47 </code>
49 To configure speech-dispatcher:
51 <code> # spd-conf
52 </code>
54 Speech-dispatcher can be started/stopped like a daemon:
56 <code> # speech-dispatcher
57 # killall speech-dispatcher
58 </code>
60 === Usage ===
62 <code> $ yasr
63 $ exit
64 </code>
66 The configuration files can be found in the /etc/speech-dispatcher or ~/.speech-dispatcher directories
67 and the yasr configuration file is located in /usr/share/yasr.
70 ===== Sticky/Slow/Mouse Keys in X =====
72 To enable the accessibility keys just edit your ///etc/slim.conf// file and logout of your X session:
74 <file>
75 default_xserver /usr/bin/Xorg
76 xserver_arguments +accessx
77 </file>
79 After you login again, to enable/disable:
80 * **Sticky keys**: Press the shift key 5 times
81 * **Slow keys**: Hold down the shift key for 8 seconds
82 * **Mouse keys**: Hold down the left shift, left Alt and Num Lock keys
84 There is also a package in the Cooking repos that can do all this in gui or command line mode: **accessx**. To install and run:
85 <code>
86 # tazpkg get-install accessx
87 $ ax help
88 $ accessx
89 </code>
