15. The apparatus of claim 12 , wherein to determine the word likelihood associated with each word in the set of the one or more words associated with a hypothesis, the processor is configured to: associate, with each word in the set of the one or more words, a corresponding measure of proximity, the measure of proximity being determined relative to words in a dictionary; and determine a likelihood for each word in the set of the one or more words based, in part, on the corresponding measure of proximity.
12. The apparatus of claim 11 , wherein to compute a normalized score in the plurality of normalized scores, the processor is configured to: determine, for each word in the set of the one or more words associated with the corresponding hypothesis, a corresponding word likelihood; and compute the normalized score for the corresponding hypothesis based, in part, on the word likelihoods of the words in the set of the one or more words associated with the corresponding hypothesis.
