This page describes a bootable CD / USB image customized for blind users. The modified version is mostly equivalent to the official "netinstall CD", but the system should start speaking as soon as you boot with it. Speech is provided via the sound card, using the eSpeak software synthesizer and the Speakup screenreader. It is also possible to use a braille display, via brltty. You can obtain the image from this page.
The image can be used with both the i686 or the x86_64 architecture. Also, it is suitable for either a recordable CD or a USB stick. Just download it and write it to the medium of your choice.
A detached GPG signature is provided on the download page. The signature is made with the gpg key associated with the address chris at the-brannons dot com. The key ID is 6521E06D. The fingerprint is 66BD 74A0 36D5 22F5 1DD7 0A3C 7F2A 1672 6521 E06D
The build system, which is a respin of the Archiso releng configuration, is maintained by Kelly Prescott and by Kyle, and the images and main website are hosted by Kyle. Thanks to Chris Brannon, the past maintainer, and to the following people for submitting valuable feedback regarding this project: Chuck Hallenbeck, Julien Claassen, Alastair Irving, Tyler Spivey, Keith Hinton, and many others. Thanks also go to Tyler Littlefield, who previously hosted the files.
Installing from the CD
The following list of steps is a brief guide to installing Arch Linux using this CD. The instructions assume that your root partition will be mounted on
- This is a dual-architecture .iso file. You can just press
enterat the boot prompt, or wait for the bootloader to time-out. Your processor should be automatically detected, and the appropriate architecture should be loaded automatically. If you have a console speaker, you will hear a beep when the boot prompt is on screen. Otherwise, wait about 10 to 20 seconds after the CD starts spinning, or about 3 to 5 seconds after the system begins to boot from USB, and then press
enterto boot the image.
- You are strongly encouraged to read the Arch Linux documentation, especially the Installation Guide and Beginners Guide. Do the installation procedure described in the Installation Guide, as modified by the instructions below.
- You'll need to install the
alsa-utilspackages. The Installation Guide mentions that you can install additional packages by appending their names to the packstrap command. For example,
pacstrap /mnt base espeakup alsa-utils
- Enable the espeakup systemd service by typing
chroot /mnt systemctl enable espeakup.service
- You also need to save the state of the sound card, so that it will be retrieved on reboot. Execute the command
alsactl -f /var/lib/alsa/asound.state storeand copy the file
alsactl -f /mnt/var/lib/alsa/asound.state storewill do this with one command.
- When you boot the system from the hard disk, it should start speaking.
The latest image includes brltty, for those who own braille displays. The brltty package available on the CD was compiled with as few dependencies as possible. It is packaged as brltty-minimal in the Arch User Repository. If you wish to use braille, you will need to supply the brltty parameter at the boot prompt. Alternatively, you can start brltty from the shell, after the system has booted.
The brltty boot-time parameter consists of three comma-separated fields: driver, device, and table. The first is the driver for your display, the second is the name of the device file, and the third is a relative path to a translation table. You can use "auto" to specify that the driver should be automatically detected. I encourage you to read the brltty documentation for a fuller explanation of the program.
For example, suppose that you have a device connected to /dev/ttyS0, the first serial port. You wish to use the US English text table, and the driver should be automatically detected. Here is what you should type at the boot prompt:
Once brltty is running, you may wish to disable speech. You can do so via the "print screen" key, also known as sysrq. On my qwerty keyboard, that key is located directly above the insert key, between F12 and scroll lock.
Maintaining Your Speech-enabled Arch Linux Installation
You shouldn't need to do anything extraordinary to maintain the installation. Everything should just seamlessly work.
Mastering Speech-enabled ISO Images
This process is now fairly straightforward. Just grab and install the talkingarch-git package from the AUR. It depends on archiso-git, so you need that as well. See /usr/share/doc/talkingarch/README for full instructions.
