TRANSITION RESTRICTIONS:

• for HTK and Julius:
  • no arc to initial state
  • no arc from final state

• Normal version of Julius:
  • should have at least one output state
  • allow only one arc from initial state
  • allow only one arc to final state (internal skip/loop is allowed)

• Multipath version of Julius:
  • should have at least one output state

In multipath version, all the transitions including model-skipping transition is allowed. However, in normal version, their transition is restricted as above.

If such transition is found, Julius output warning and proceed by modifying transition to suite for the restriction.

関数

static int trans_ok_p (  HTK_HMM_Trans *  t  )  [static]

Scan the transition matrix to test the ristrictions. 引数: t  [in] a transition matrix to be tested 戻り値: 0 if it conforms, 1 if unacceptable transition was found and modification forced, 3 if totally unsupported transition as included and cannot by handled. check_hmm_restriction.c の 75 行で定義されています。 参照元 check_hmm_limit().

boolean check_hmm_limit (  HTK_HMM_Data *  dt  )

Check if the transition matrix conforms the ristrictions of Julius. 引数: dt  [in] HTK HMM model to check. 戻り値: TRUE on success, FALSE if the check failed. check_hmm_restriction.c の 209 行で定義されています。 参照元 check_all_hmm_limit().

boolean check_all_hmm_limit (  HTK_HMM_INFO *  hmminfo  )

Check all the HMM definitions in a HTK HMM definition data. 引数: hmminfo  [in] HTK HMM data to check. 戻り値: TRUE if there was no bad models, FALSE if at least one model is bad. check_hmm_restriction.c の 242 行で定義されています。 参照元 rdhmmdef().
