Welcome to the OpenMary development page

This is the home of the source code of the OpenMary text-to-speech synthesis system.

For an introduction to MARY, online demos, and for downloading an installer for the MARY system, go to the main MARY page.

On these development pages, you can browse the source code, and submit bug reports (but look at the existing bug reports first!).

SVN access to the repository

You can check out the source code from SVN, using the following command:

   svn checkout openmary

The source code of released versions can be found below tags/, e.g. to check out the source code of the "4.0 beta" release, do this:

   svn checkout openmary-4.0beta

Bug reports

If you think you have identified a bug, proceed as follows:

  1. Check in the list of known bugs whether the bug has been reported already;
  2. If you cannot find it, create a new ticket containing the following information:
    • operating system and java version used;
    • what to do to reproduce the error;
    • expected behaviour;
    • detailed log files, i.e. an excerpt of MARY TTS/log/server.log containing the error episode.
  3. Discuss the problem on the MARY user mailing list.


People interested in adding support for a language can get in touch, e.g. via the MARY developers mailing list.

Mailing List

If you use the MARY system, you can subscribe to the mary-users mailing list. Topics that should be discussed here include:

  • How to use the MARY system: run the server, start the client, save audio, run MARY in standalone mode, etc.
  • Suggestions for improvement, bug reports, feature requests (no guarantees of course that anyone has time to do it).

The MARY developers mailing list is for discussions around the MARY TTS source code:

  • Improvements of the core MARY code;
  • issues around attempts to build new language components and voices;
  • issues arising when integrating MARY TTS into other code.

Want to help?

As all open source projects, OpenMary can only thrive with contributions from the community.

Any pronunciation corrections are welcome on the PronunciationCorrections page.

If you have a suggestion what you would like to implement, it might be a good idea to discuss it on the mary-users list, and/or to submit a ticket.

If you would like to help but would need inspiration what you could do, do take a look at the active tickets, or more specifically at the section Volunteers wanted!

Contact Marc Schröder (schroed at if you want to get write access to the repository.
