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
|
|
Trinity Control Center or start it with the command "tdecmshell kcmkttsd".
|
|
|
|
tdetexteditor_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 tdebase/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.
|
|
* Filter plugins for converting chat emoticons to speakable words,
|
|
fix mispronunciations, and convert xhtml to SSML.
|
|
* Audio output via aRts, ALSA, GStreamer (version 0.8.7 or later),
|
|
or aKode.
|
|
|
|
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.
|
|
|
|
Audio Plugins
|
|
-------------
|
|
KTTS can be built with the following audio plugins. The "Default Configure
|
|
"Option" column shows the default option for the configure command.
|
|
The "Alternate" column gives the opposite configure option:
|
|
|
|
System Plugin Default Configure Option Alternate
|
|
------ ------------ ------------------------- ------------------------
|
|
aRts artsplayer --with-arts --without-arts
|
|
ALSA alsaplayer --with-alsa=check --with-alsa=no
|
|
GStreamer gstplayer --with-gstreamer=no --with-gstreamer=check
|
|
aKode akodeplayer --with-akode=no --with-akode=check
|
|
|
|
You *must* have at least one of these plugins for KTTS to work.
|
|
|
|
The aKode and GStreamer players are not built by default because they have issues
|
|
with instant stopping and starting.
|
|
|
|
Packager Notes
|
|
--------------
|
|
The following speech synthesizer plugins are all built by default.
|
|
Some of them are runtime only dependent upon non-free software.
|
|
(Non-free according to Debian Policy). The "Configure Option to
|
|
not build" column shows the configure command to not build the plugin:
|
|
|
|
Synth License Configure Option to not build
|
|
------------- -------- -----------------------------
|
|
Festival free --disable-kttsd-festivalint
|
|
Festival Lite free --disable-kttsd-flite
|
|
Epos free --disable-kttsd-epos
|
|
Command free --disable-kttsd-command
|
|
Hadifix non-free --disable-kttsd-hadifix
|
|
FreeTTS non-free --disable-kttsd-freetts
|
|
|
|
IMPORTANT NOTE TO BINARY PACKAGERS:
|
|
Please do not distribute binary packages of tdeaccessibility with the
|
|
gstreamer plugin, as this creates unwanted dependencies. Instead,
|
|
distribute the gstreamer plugin in a separate package, e.g.
|
|
kde-accessibility-extras. The separate package should require
|
|
gstreamer >= 0.8.7. Thank you.
