When training (-t) HERest may inexplicably fail with return code -11. This usually indicates that at least one label file is simply empty (modulo whitespace). HTK says it clearly to stderr, but check_call eats that error. Best thing to do would be to wrap something or other in a try: except for CalledProcessError and then print stderr before dying?
