Need to review creation of sp hmm in  Step 7 - Fixing the Silence Models to figure out why this error is appearing:

Warning: HMM "sp" has unsupported arc.
SERIOUS WARNING: Transition arc has been modified as below
SERIOUS WARNING: This may cause unintended recognition result

Seems to have no noticeable effect on recognition.

This is a known limitation of Julian, need to use multi-path version of Julian.

Normal version of Julius/Julian assumes that all the transition matrix
in hmmdefs have only one arc from initial state and only one arc to
final state, and should not have direct transition from initial state
to final state in a model. This is a known limitation of normal
version of Julian.

There is an another version of Julius/Julian called "multi-path version"
that enables arbitrary trantision (the decoding will become slower instead).

See Issue #2

VoxForge now uses multi-path version of Julius/Julian.
