KTTS -- KDE Text-to-Speech -- is a subsystem within the KDE desktop
for conversion of text to audible speech. KTTS is currently under
development and aims to become the standard subsystem for all KDE
applications to provide speech output. Currently, KTTS consists of
the following components:

KTTSD
  The KDE Text-to-Speech Deamon, a non-gui application that runs in
the background, providing TTS support to KDE applications. Applications
initiate TTS by making DCOP calls to kttsd.

KTTSMGR
  An application for configuring the KTTS System and for managing in-progress
speech jobs. kttsmgr provides an icon in the system tray for performing
these functions as needed.

kttsjobmgr
  A KPart for managing in-progress speech jobs.

kcmkttsd
  A KControl module for configuring the KTTS System. kcmkttsd runs in the
KDE Control Center or start it with the command "kcmshell kcmkttsd".

ktexteditor_kttsd
  A plugin for the KDE Advanced Text Editor that permits you to speak an entire
text file or any portion of a file.

khmtl-plugin
  A plugin for Konqueror that permits you to speak all or any portion of an
HTML web page.  (Note: this component is in kdebase/konqueror/kttsplugin)

User features:
  * Speak contents of a text file.
  * Speak KDE notification events (KNotify).
  * Speak all or part of the text of a web page in Konqueror.
  * Speak all or part of the text in Kate text editor, including
    instances where Kate is embedded in another KDE application.
  * Long text is parsed into sentences. User may backup by sentence
    or paragraph, replay, pause, and stop playing.
  * Audio output via aRts or GStreamer (version 0.8.7 or later)

Programmer features:
  * Priority system for screen reader outputs, warnings and messages,
    while still playing regular texts.
  * Plugin-based architecture for support of a wide variety of speech
    synthesis engines and drivers.
  * Permit generation of speech from the command line (or via shell scripts)
    using the KDE DCOP utilities.
  * Provide a lightweight and easily usable interface for applications
    to generate speech output.
  * Applications need not be concerned about contention over the speech device.
  * FUTURE: Provide support for speech markup languages, such as VoiceXML, Sable,
    Java Speech Markup Language (JSML), and Speech Markup Meta-language (SMML).
  * FUTURE: Provide limited support for embedded speech markers.
  * Asynchronous to prevent system blocking.

Requirements
------------
KDE 3.2 or greater and a speech synthesis engine, such as Festival.  Festival
can be obtained from http://www.cstr.ed.ac.uk/projects/festival/.  Festival
is distributed with most Linux distros.  Check your distro CDs.  Also works
with Hadifix, Epos, Festival Lite (flite), FreeTTS, or any command that can
speak text.

Optional Components
-------------------
  * The sox utility is needed for adjusting overall speech rate.
  * The xsltproc utility is needed for SSML support.
  * GStreamer 0.8.7 or greater.

See the KTTS Handbook

  (http://accessibility.kde.org/developer/kttsd/handbook/index.html)

for complete instructions on installing, compiling, configuring, and using
KTTS.

IMPORTANT NOTE TO BINARY PACKAGERS:
Please do not distribute binary packages of kdeaccessibility with the
gstreamer plugin, as this creates unwanted dependencies.  Instead,
distribute the gstreamer plugin in a separate package, e.g.
kde-accessibility-extras.  Thank you.

To build KTTS with the gstreamer audio plugin add the following option
to your configure command:

  --enable-kttsd-gstreamer

In addition to the KDE Bugzilla database (bugs.kde.org), discussions for KTTSD
currently take place in the kde-accessibility mailing list.  Subscribe at
https://mail.kde.org/mailman/listinfo/kde-accessibility.  Developers
also hang out in IRC (irc.kde.org channel #kde-accessibility).
