java.lang.Objectedu.cmu.sphinx.result.MAPConfidenceScorer
Computes confidences for the highest scoring path in a Result.
The highest scoring path refers to the path with the maximum
a posteriori (MAP) probability, which is why this class is so named.
Note that this MAPConfidenceScorer creates a
Lattice
from the result first, which means
that you should only use this confidence scorer if the result is created
from the LexTreeLinguist
and the
WordPruningBreadthFirstSearchManager
.
