Speech Dispatcher 0.5 Released
The Brailcom organization is happy to announce the availability of
Speech Dispatcher 0.5 developed as a part of the Free(b)Soft
* What is Speech Dispatcher?
Speech Dispatcher is a device independent layer for speech
synthesis, developed with the goal of making the usage of speech
synthesis easier for application programmers. It takes care of most
of the tasks necessary to solve in speech enabled applications. What
is a very high level GUI library to graphics, Speech Dispatcher is
to speech synthesis.
The architecture of Speech Dispatcher is based on a proven
client/server model. The basic means of client communication
with Speech Dispatcher is through a TCP connection using the Speech
Synthesis Interface Protocol (SSIP).
Key Speech Dispatcher features are:
- Message priority model that allows multiple simultaneous
connections to Speech Dispatcher from one or more clients
and tries to provide the user with the most important messages.
- Different output modules that talk to different synthesizers
so that the programmer doesn't need to care which particular
synthesizer is being used. Currently Festival, Flite, Epos and
(non-free) Dectalk software are supported.
- Client-based configuration allows users to configure different
settings for different clients that connect to Speech Dispatcher.
- Simple interface for programs written in C, C++ provided through a
shared library, Common Lisp and Guile interface. Full
Python interface is newly available. An Elisp library is
developed as a sperate project speechd-el. Possibly an interface
to any other language can be developed.
* What is new in 0.5?
- SSIP now supports SSML (Speech Synthesis Markup Language) messages.
- Communication with Festival is highly improved.
- Improved DTK Software Synthesis support.
- Python interface library now supports full SSIP.
- Various bugfixes.
NOTE: The communication mode of the Festival output module (SSML mode)
is incompatible with the previous festival-freebsoft-utils releases.
You need to install festival-freebsoft-utils 0.3 or higher to be able
to run Speech Dispatcher with Festival!
* Where to get it?
You can get the distribution tarball of the released version from
You also need to get festival-freebsoft-utils in version 0.3 or newer
We recommend you to fetch the sound icons Speech Dispatcher can use as
well. They are available at
