I've downloaded the Spanish Voxforge Acoustic Model and I'm trying to use it with the test language model that came with it. However, I keep receiving the following errors:

12:27:52.901 SEVERE lexTreeLinguist Bad HMM Unit: V

12:27:52.909 SEVERE HMMTree Missing HMM for unit E with lc=V rc=R

12:27:52.909 SEVERE lexTreeLinguist Bad HMM Unit: V

12:27:52.909 SEVERE HMMTree Missing HMM for unit N with lc=O rc=V

12:27:52.909 SEVERE lexTreeLinguist Bad HMM Unit: V

12:27:52.909 SEVERE HMMTree Missing HMM for unit V with lc=N rc=E

 

 

I receive dozens of errors like this. Is the problem with my config.xml file? I've pasted it below for viewing:
