Speech Dispatcher 0.6.4
The Brailcom organization is happy to announce the availability
of Speech Dispatcher 0.6.4 developed as a part of the Free(b)Soft
project. This is a minor release, it contains mostly bugfixes and
minor improvements. Please read `What is new' and `NOTES' bellow.
* 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, Espeak
and (non-free) Dectalk software, IBM TTS are supported. Festival
is an advanced Free Software synthesizer supporting various
languages. Espeak is a very fast multi-lingual synthesizer.
- 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. Python, Common Lisp and Guile interface. An Elisp
library is developed as a sperate project speechd-el. Possibly an
interface to any other language can be developed.
