Hi donmehdi

You should really start a new thread since your question has nothing to do with this thread.

Take a look at http://voxcommando.com/mediawiki/index.php?title=Main_Page#Selecting_a_language

If you still need help please let us know what version of VoxCommando you are using (version number and whether you are using standard or SP version) and what version of Windows you are using.

Thanks James i found my answer in your video after passing trough all the others in that one, VoxCommando 2 - Getting started with MS Speech Platform 11.
Now i can use different languages for speech. But it seems that payloads dictation doesn t work.

Correct.  As documented, the SP version does not support dictation.

is there gonna be an update fixing that ?

It is not something that can be "fixed".  It is the nature of that speech engine.

If you want dictation you must use the non-SP version.
