Speech Dispatcher 0.6.7
The Brailcom organization is happy to announce the availability
of Speech Dispatcher 0.6.7 developed as a part of the Free(b)Soft
project. This is a minor release. 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.
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 separate project speechd-el. Possibly
an interface to any other language can be developed.
* What is new in 0.6.7?
- Setting of preferred audio output method is now centralized in
speechd.conf instead of being scattered around the various
output module configurations.
- 'spd-conf' configuration, diagnostics and troubleshooting tool
now makes it easy to create a user configuration for Speech Dispatcher
or to send a request for help with all appropriate logging information
- Dummy output module which attempts to play a pre-recorded help
message via various sound systems when all other modules fail
- Possibility to switch on verbose logging over SSIP
for easy debugging and bug-reporting from client applications
- Volume settings in Pulse Audio and avoidance of having to reopen
the PA connection on every synthesis request
- Punctuation mechanism in IBM TTS is now configurable
- New generic output modules for Espeak with Mbrola
and for Cepstral Swift.
- There are changes in the configuration file since the previous
release. It is highly recommended to replace your speechd.conf
file with the speechd.conf provided in this package and copy your
settings there if you are upgrading from 0.6.6 or any older
versions. The old configuration file should also work, but
audio output method settings will in output modules configuration
will have no effect.
- By default, the communication port of Speech Dispatcher is only
opened for localhost connections. Please see the
LocalhostAccessOnly option in speechd.conf for information on how
to allow connections from other manchines as well.
