New EULER modules and/or databases

EULER has been designed in such a way that third parties can safely contribute to it, by providing additional modules and/or databases. This enables EULER to provide an ever growing set of languages.

EULER modules can be distributed in two forms. The GNU C++ form is prefered when possible (i.e., when a module does not include important intellectual property, or when its designer is willing to release this IP). DLLs are always provided anyway. WinEULER comes with a complete EULER Module Developer's Guide, in which we give details on how to interface a C++ module with EULER (sample modules are also provided). As a result, third parties can quickly develop new modules, or adapt proprietary modules to EULER. These modules can be made available to EULER users, for non commercial, non military use.

EULER databases are made available in compact format, so as to minimize the disk space required by a multilingual TTS, and to ensure that databases cannot easily be reverse-engineered. EULER modules, however, are always able to read non-compacted databases, too. Consequently, third parties can privately develop their own (non-compacted) databases, and later safely make them available in a compact format in the context of the EULER project. Compaction is performed by the developer of the related EULER module.

All commercial rights on modules and databases provided by third parties remain with them. Modules and databases provided by third parties are copyrighted by their designers.

All these details are fixed by some official agreement before people send us anything.
