See this entry in trac: Ticket #449 - HowTo error

Just thought I would share a minor issue with you regarding the howto - in one of my projects I neglected to establish a directory called acoustic_model_files to receive hmmdefs and tiedlist. Interestingly the scripts created a single file called acoustic_model_files instead of the directory, and the error is not found until you run julius to test and he complains he cannot find hmmdefs etc. It looks as though the directory is there but in fact it is not. When I deleted the bogus file, created the directory and ran the setup again all was well.
