4.2.8 Network Decoding:
Language Model File
The language model file defines the overall structure of the language
being used. The network decoding process relies on this file for
help with constructing a hypothesis for an utterance. The
statistical model pool, introduced in the
next section,
contains the
definition of a state. The language model provides instructions
for using these states along with the other levels of the language
model in order to build a hypothesis for a given utterance.
The language mode file is created using the isip_network_builder
utility. This utility allows the user to build a language model
from the ground up. The language modeling process is discussed
in
Section 6.2.
The language model descends from the word level. The
middle level is called the phone level and the lowest level is
the state level (See the figure to the right). For a more detailed
explanation of the language model and the language modeling process,
see
Section 6.
