|
* Description:
|
|
* This file defines the model state data structure. The state
|
|
* data structure contains indices of model parameters associated
|
|
* with the state and it contains adjacency lists of prior states
|
|
* and next states.
|
|
*
|
|
* The states defined in this structure are in the context of
|
|
* an utterance HMM built to model a whole utterance. Hence it
|
|
* is built as a network of subword HMM's.
