5.5.3 Cross-Word CD Models: State-Tying
The process of state-tying for cross-word context dependent models is similar to the process for word internal models. For a more detailed explanation of this process, go to Section 5.4.3. From the directory
Command: isip_recognize -param param_state_tying.sof -verbose all Version: 1.23 (not released) 2003/05/21 23:10:45 *** no audio database file was specified *** *** no symbol graph database file was specified *** *** no transcription database file was specified *** loading front-end: $ISIP_TUTORIAL/recipes/frontend.sof loading language model: $ISIP_TUTORIAL/models/xword_phone_models/lm_xword_jsgf_train.sof loading statistical model pool: $ISIP_TUTORIAL/models/xword_phone_models/smp_xword_train.sof loading configuration file: $ISIP_TUTORIAL/sections/s05/s05_05_p03/config.sofNext, the tied states must be generalized to unseen context in the training data. Run the command:
Command: isip_recognize -param params_xword_test.sof -verbose all Version: 1.23 (not released) 2003/05/21 23:10:45 *** no audio database file was specified *** *** no symbol graph database file was specified *** *** no transcription database file was specified *** loading front-end: $ISIP_TUTORIAL/recipes/frontend.sof loading language model: $ISIP_TUTORIAL/models/xword_phone_models/lm_xword_jsgf_tied.sof loading statistical model pool: $ISIP_TUTORIAL/models/xword_phone_models/smp_xword_tied.sof loading configuration file: $ISIP_TUTORIAL/sections/s05/s05_05_p03/config.sofThis step will add the state-tied models not seen in the training context. The resulting model file will be larger than the original. Once the states have been tied, the models must be trained again. |
