5.5.2 Cross-Word CD Models: Triphone Training
Once the triphone models have been generated, they must be trained. Go to the directory:

Notice that the context_mode is now CROSS_SYMBOL instead of SYMBOL_INTERNAL. This is because we are training cross-word context dependent models instead of word-internal models. The rest of the parameter file is the same as the word-internal parameter file. The next step is state-tying. |
