Emacspeak, The World's Fonts And Braille

Emacspeak has supported the editing of Unicode text for over a year now --- thanks to the patches fromLukas. With the support now mature, I have now retired option emacspeak-unibyte --- Emacspeak no longer supports running Emacs in unibyte mode. Note that this aligns Emacspeak with Emacs 23.2 which obsoletes unibyte mode.

When you edit text containing Unicode characters, Emacspeak uses the name of the character as found in the description file from the Unicode consortium --- you will need to download and install that data file as documented in Emacs:

describe-char-unicodedata-file is a variable defined in `descr-text.el'.
Its value is 
"/usr/local/share/unicode/UnicodeData.txt"

Documentation:
Location of Unicode data file.
This is the UnicodeData.txt file from the Unicode Consortium, used for
diagnostics.  If it is non-nil `describe-char' will print data
looked up from it.  This facility is mostly of use to people doing
multilingual development.

This is a fairly large file, not typically present on GNU systems.
At the time of writing it is at the URL
`http://www.unicode.org/Public/UNIDATA/UnicodeData.txt'.

You can customize this variable.

This variable was introduced, or its default value was changed, in
version 22.1 of Emacs.

With the Unicode data file in place, Emacspeak can announce names of characters from all of the world's fonts --- this includes Braille. As an added convenience, I have integrated package toy-braille.el found on the Emacs wiki into the Emacs codebase and defined a new interactive command emacspeak-wizards-braille --- if you find yourself using it often, you can bind it to a key of your choice. Command emacspeak-wizards-braille prompts for the string to Braille and produces a Grade-1 representation of the specified string using the appropriate Unicode characters.

Emacspeak Servers --- Catching Up With Debian And Ubuntu

Over the last couple of years, the TCL world has moved on from TCL8.3 to TCL8.4 --- this introduces a set of needed changes to how Emacspeak servers such as Espeak and ViaVoice-Outloud work. I have finally decided to break backward compatibility with TCL8.3 and move things forward to TCL8.4, now that all the Linux distributions have settled on TCL8.4.

Also, sometime in 2005, I transitioned all of the server Makefiles to use libtool --- at the time, it made compilation of the servers somewhat easier. However, this has tended to make things more complex over time, thanks to changes in libtool. I've now dropped the libtool dependency in favor of using simpler Makefiles --- thanks William Hubbs of Gentoo!

ViaVoice Outloud Server For Emacspeak

The Voxin package from Guilles continues to be the easiest means of obtaining high-quality text-to-speech on Linux. Installation of that package went smoothly on Hardy; however on Jaunty, things did not go so well, see notes below for things to watch out for on Jaunty or later.

  • The libstdc++ compat libraries ended up not getting installed on Jaunty. Consequence, ViaVoice produces a warning asking you to install the ViaVoice RTK, even though it's already installed. I ended up rescueing the compat libs from my Hardy build. Perhaps we should put up a simple tar.gz file that drops those libs into /usr/lib?
  • Alsa is configured to use pulseaudio on Jaunty. An unfortunate consequence is that when ViaVoice runs, it sounds like a stereo channel played as mono, i.e. the speech slows down and the voice sounds wrong. The fix is to create a .asoundrc file in your home directory --- you can use the sample in linux-outloud/ASOUNDRC as a starting point. To see if pulseaudio is intervening in your setup, do :aplay -v wav file --- to see the set of alsa plugins that are participating in audio output.

ESpeak And Emacspeak

The ESpeak server does not get affected by the above problem. However, unless you install package alsa-oss and invoke that server as :aoss tcl espeak the server will fail to start if some other application is using the audio device.

Software Dectalk And Emacspeak

This still needs testing under newer Linux distributions --- I've not used it in a long time and dont have the libs installed any more.

Launching Favorite Media Via Hot Keys

Launching Oft-Played Media On The Complete Audio Desktop

Command emacspeak-multimedia lets you launch all forms of local and remote media. However this stil requires you to specify the media location --- and this requires a bunch of keystrokes that you end up repeating for selecting media that you play often, e.g., from your private music collection. No more extra keystrokes, you can now have Emacspeak automatically assign suitable hotkeys for launching emacspeak-media on your favorite audio collections.

How It Works

  • Customize Emacspeak option emacspeak-media-location-bindings using Emacs' Custom interface:
    M-x customize-variable --- 
    
    press C-H V in emacspeak.
  • Click ins to insert a key/location pair.
  • Click save to persist the binding.
  • pressing the assigned hotkey will automatically launch emacspeak-multimedia on the predefined location --- emacs will prompt you with regular filename completion for media resources found in that directory.

In my own case, I have favorites defined on hyper-<n> so I can define upto 10 hotkey assignments for media locations.Once launched, Emacspeak automatically switches to the media player buffer; note that this is different from how emacspeak-multimedia normally works. The justification: this hotkey interface is ideally suited to remote controls, joysticks, and any other peripheral via which you can deliver input to Emacs.

Looking Beyond The Screen At Google I/O2009

Come join me and Charles Chen at Google I/O2009 at our session on Looking Beyond The Screen (YouTube Preview where we will describe some of our work on eyes-free interaction on Android. We'll be around during most of Google I/O, so if you are interested in eyes-free interaction ranging from Emacspeak to Fire-Vox, or anything else eyes-free, feel free to grab us in the hallways. Looking forward to seeing you there!

Abstract: Looking Beyond The Screen

Looking Beyond The Screen

Project Eyes-Free aims to enable fluent eyes-free use of mobile devices running Android. Target uses range from eyes-busy environments like in-car use to users who are unwilling to or incapable of looking at the visual display --- see For The Blind, Technology Does What A Guide Dog Can't, NYTimes, January 4, 2009, for a high-level overview. As described in that article, we are releasing components from project Eyes-Free as they become ready for end-user deployment. This announcement marks the first public release of the eyes-free shell on the Android Marketplace, though the underlying source code has been available for some time from the code repository at Google Code Hosting.

Here is a brief overview of the end-user affordances provided in this release:

  1. An Eyes-Free Shell for conveniently launching talking applications.
  2. A collection of useful talking applications that turn an Android phone into an eyes-free communication device --- see subsequent sections for an overview of these applications. Note that thes eapplications have been written to be both useful to end-users as well as to help the developper community to come up to speed with developing eyes-free applications for Android.

We will be uploading video tutorials demonstrating the use of these applications to YouTube --- please see the project Web site for these links as they become available.

Talking Dialer

A key innovation is the use of the touch screen to enable one-handed, eyes-free dialing of phone numbers using the touch screen --- see Miguel Helft's NY Times article cited above for a good layman's description of the technique. The talking dialer comes with a talking phone-book that enables users to quickly select a desired contact using the touch screen.

Knowing Your Location

This mini-application announces your present location based on information acquired via GPS and the cell network. It speaks your current heading using the built-in magnetic compass, looks up the current location on Google Maps, and announces the location in terms of a nearby address and street intersection.

Device State

This mini-application announces useful information such as battery state, signal strength, and availability of WiFi networks.

Date And Time

This mini-application provides single-touch access to current date and time.

Toward an Accessible Democracy --- White House Moderator AxsJAXed

Toward An Accessible Democracy --- White House Moderator AxsJAXed!

This is not directly Emacspeak related --- except that it is useful for emacspeak users. Project AxsJAX, combined with Fire-Vox does for Web-2.0 applications what Emacspeak does for applications written within Emacs. Charles and I just announced AxsJAX For White House Moderator --- an AxsJAX extension that applies W3C ARIA to the White House Moderator.I'll append the article below:

An ARIA For The White House Moderator

Google-AxsJAX was launched in late 2007 as a library for access-enabling Web-2.0 applications. Since then, we have released accessibility enhancements for many Web-2.0 applications via the AxsJAX site as early experiments that have eventually graduated into the products being extended. Today, we are happy to announce an early AxsJAX extension for Google Moderator that enables fluent eyes-free use of Google Moderator as seen on the White House site.

HowTo: Brief Overview.

For details on installing and using AxsJAX extensions, see the AxsJAX FAQ. Briefly, you need Firefox 3.0 and a screenreader that supports W3C ARIA. Users who do not have a screenreader installed can most easily experience the results by installing Fire Vox, a freely available self-voicing extension for Firefox.

With the AxsJAX extension in place, you can use Google Moderator via the keyboard, with all user interaction producing spoken feedback via W3C ARIA. Here is a brief overview of the user experience:

  1. The user interface is divided into logical panes --- one listing topic areas, and the other listing questions in a given topic. At times, e.g., before a meeting, you may find an additional Featured Question pane that shows a randomly selected question that you can vote on.
  2. Users can ask new questions under a given topic, or give a thumbs-up/down to questions that have already been asked.
  3. Use the left and right arrow keys to switch between the two panes. You hear the title of the selected pane as you switch.
  4. Use up and down arrows to navigate among the items in the selected pane. As you navigate, you hear the current item.
  5. Hit enter to select the current item.
  6. The current item can be magnified by repeated presses of the + (or =) key. To reduce magnification, press the - key.
  7. When navigating the questions in a given topic, hit y or n to vote a question up or down.
  8. When navigating items in the topic pane, hit a to ask a question. Once you confirm your request to post the question, it will show up in the list of questions for that topic so that others can vote that question up or down.

Please use Google Group Accessible for providing feedback on this AxsJAX extension.

Share And Enjoy--

Emacspeak Webspace Goodies

Module emacspeak-webspace has a few new goodies on offer. If you activate WebSpace Headlines to obtain a continuously updating ticker of headlines, you may also at times want to find one of the headlines you heard go by and read the relevant article. Command emacspeak-webspace-headlines-view bound by default to C-RET pops up a special Headlines buffer that lists all the currently available headlines. This is a regular Emacs buffer that uses a special major mode called emacspeak-webspace-mode. This mode provides special commands to open a feed at point, follow hyperlinks etc.; use Emacs' online help facilities to learn how this buffer works.

Mode emacspeak-webspace-mode is also used to advantage in browsing information retrieved via the Google AJAX APIs described in the previous set of articles on this blog. Google Reader subscribers can now view the subscription list in a Webspace buffer via command emacspeak-webspace-reader. Additionally, command emacspeak-webspace-google provides a more convenient interface to command gweb-google-at-point --- in addition to speaking the snippet from the first search hit, this command places the first four results in a special Search Results buffer that is put in Webspace mode.

Emacspeak-WebSpace Just Got A Lot Faster

In Praise Of Google AJAX APIS

New module gfeeds.el (part of Library g-client) now implements a Lisp interface to the Google AJAX FeedSearch API. An immediate consequence of this is that module Emacspeak-WebSpace just got orders of magnitude faster --- not that it was slow to start with:-)

In Praise Of The Google Search AJAX API

In Praise Of The Google AJAX Search API

Emacspeak has always provided Google Search with a single keystroke from anywhere on the audio desktop. But with the coming of the Google AJAX Search API it becomes possible to integrate Google Search at a far deeper level into your fingertips! The AJAX API demonstrates the true speed of Google Search, since you dont need to wait for an HTML page to download and render --- results are served as a light-weight JSON data structure.

What You Can Now Do

Module gsearch (part of the g-client package) provides an interactive command gsearch-google-at-point --- I have this bound to key hyper-/ in Emacs. Executing this command from anywhere inside Emacs does the following:

  • Grabs word under point, and prompts in the minibuffer for a search-term --- with the word we just grabbed as the default.
  • Fetches other relevant search terms in the background via Google Suggest, and makes these available via Emacs' minibuffer history mechanism. Use keys M-n and M-p to cycle through these if needed.
  • Hitting ENTER performs a Google Search using the AJAX API, and displays the title and content snippet for the first search result.
  • Executing command gsearch-google-at-point subsequently at the same location opens the first search result.

Tutorial: Enhancing Web 2.0 Usability Using AxsJAX

You can watch a video of the tutorial Charles and I gave as part of the Google Open Source series on July 14. Emacspeak users can play the video by pressing e e on the above link and specifying emacspeak-m-player-youtube-player when prompted.

Abstract

Google is the Web's premier creator of user-friendly Web 2.0 applications, and I have long viewed it as part of our mission to do for users in the long tail (AKA users with special needs) what we've achieved for the mainstream user. Accessibility 2.0 is now a hot topic on the Web --- and we would like to move from a world where AJAX applications were a straight No-No with respect to blind users to a world where these same technologies are used to enhance their usability for everyone.

Google-AxsJAX is an Open Source framework for injecting accessibility for users with special needs --- and more generally, usability enhancements --- into Web 2.0 applications. In this TechTalk, Charles Chen and I give a hands-on tutorial on using AxsJAX to enhance the usability of Web 2.0 applications. The tutorial covers the following:

  • A brief introduction to the additional opcodes introduced by W3C ARIA to the assembly language of the Web (AKA HTML+JavaScript).
  • AxsJAX library abstractions built on the above that help Web developers generate relevant feedback via the user's adaptive technology of choice.
  • Steps in creating fluent eyes-free interaction to Web applications, including enabling rapid access to parts of a complex Web page.

This tutorial focuses on solutions we've already built and deployed both within shipping products and as early end-user experiments. Google products that we will cover include:

  • Google WebSearch
  • Google Reader
  • Google Books
  • GMail and Google Talk
  • Google Scholar
  • Google Sky

And time permitting, we might even demonstrate how I now make up for all the time I save thanks to an efficient eyes-free auditory user interface by playing JawBreaker and reading XKCD via their AxsJAXed versions.

Note that writing AxsJAX enhancements to Web applications can help you win bragging rights and cool swag! The goal of this hands-on tutorial is to help you get there faster!

ProcEd: A Speech-Enabled Task Manager For Emacs

For the last 10 years or so, view-process-mode has been my task manager of choice for monitoring and controlling the state of processes on the Emacspeak audio desktop. As of Emacs 23, AKA Emacs from CVS, that module does not work anymore --- in fact it has not been updated for several years. On the positive side, Emacs now bundles module ProcEd --- a task manager that does for processes what module DirEd does for files and directories. As of this morning, proced.el is fully speech-enabled by Emacspeak. You can install module ProcEd for Emacs 22 by obtaining the file from the Web --- you can easily find it via Google.

Share And Enjoy ... And have a great July 4th Holiday!

Talk Details

Leveraging Web 2.0 Design Patterns For Enhanced Accessibility T. V. Raman (Google)

HTML DOM+ JavaScript constitutes the assembly language of Web Applications. Access To Rich Internet Applications --- ARIA --- adds in a couple of additional op-codes for helping Web applications better communicate with adaptive technologies such as screenreaders. How do we now push the envelope with respect to Web applications and adaptive technologies such as screenreaders and self-voicing browsers in a manner similar to what we as Web developers have collectively achieved for the mainstream user? This session will demonstrate programming techniques that help Web developers experiment with and build in the latest accessibility techniques into their Web applications. We will base this session on project Google-AxsJAX. Developers should know JavaScript, but session doesn't require deep AJAX hackery.

Emacspeak On Thinkpad X-61 Running Gutsy (Ubuntu 7.0)

I recently upgraded to a Thinkpad X-61 running Gutsy --- here are some brief notes on the move. In summary, all is well, and I like Gutsy running on the X-61.

Here are things to be aware of both from a hardware and software perspective. All of this is with X and GNOME turned off; note that some of the tips e.g. turning off the display as described here, will cause havoc with X.

  • The X-61 display can be turned off using vbetool
    vbetool dpms off

    for turning off the display, and
    vbetool dpms on

    for turning it back on again.
  • If you suspend to memory etc., make sure to add the appropriate vbetool command to the relevant script in /etc/acpi/resume.d.
  • Gutsy is running ALSA 1.0.15, and to date, I've not had any trouble with the ViaVoice Outloud TTS engine in this environment. Make sure to play with amixer --specifically run command
    amixer controls

    to understand all the various switches and controls exposed by the audio hardware on the X61. Here are some of the things that were noticeably different that are worth mentioning:
    1. The PC speaker can now be manipulated via ALSA.
    2. The X-61 has two input sources. If you plug in an external mike, make sure to set both input sources to the microphone --- as opposed to leaving one or both of them to be either internal mic or mix. Specifically, plugging in an external mike does not disable the internal microphone.
    3. For some bizarre reason, it's possible to turn off the headphone output--- but you cannot control its gain.
  • Kernels later than 2.6.21 do much better with respect to power management, and this really shows on the X-61. With the LCD off, my X61 claims it'll run for 7.5 hours; if you turn off the wireless and USB1.1 as well, it claims it can go for over 8.5 hours.
  • Emacs versions: I'm running out of CVS AKA Emacs 23--- but the emacs-snapshot or emacs22 Ubuntu packages appear to mostly work as well. One irritation with some of the prepackaged bundles of Emacs under Ubuntu is that they dont install the Emacs Lisp sources, and this will bite if you try compiling packages like Emacs/W3.

All in all, the upgrade to Gutsy was mostly painless --- other than having to figure out the usual nits about the new hardware. The /proc/acpi/ibm support is further along but not yet complete--- as an example /proc/acpi/ibm/video does not yet control the state of the LCD --- and you cannot query the state of the display reliably through that interface.
