Julius uses the HTK models. To build the Sphinx ones we need sphinx-train (which isn't packaged yet, but we've got some test packages) and some scripts that Pete wrote. https://launchpad.net/voxforge-sphinx-train/ We haven't gone through a license audit on those yet, but I don't expect any issues. That is an interesting question though, is there a "binary blob" argument if we built the models offline and not in the source packages? It would seem like as long as it was documented and used free tools there wouldn't be an issue. Ted
