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

Run the command:

The resulting model file will be larger than the original. Once the states have been tied, the models must be trained again. |
