Introduction

This is the Speech Dispatcher project (speech-dispatcher). It is a part of the Free(b)soft project, which is intended to allow blind and visually impaired people to work with computer and Internet based on free software.

Speech Dispatcher project provides a high-level device independent layer for access to speech synthesis through a simple, stable and well documented interface.

Complete documentation may be found in doc directory. Read doc/README for more information. This documentation is also available online.

The SSIP communication protocol is also documented.

The key features and the supported TTS engines, output subsystems, client interfaces and client applications known to work with Speech Dispatcher are listed in overview of speech-dispatcher as well as voices settings and where to look at in case of a sound or speech issue.

Mailing-lists

There is a public mailing-list speechd@lists.freebsoft.org for this project.

This list is for Speech Dispatcher developers, as well as for users. If you want to contribute the development, propose a new feature, get help or just be informed about the latest news, don't hesitate to subscribe. The communication on this list is held in English.
