The counts are weighted be the POSTERIOR probabilities of the ngrams,
as obtained from adding and normalization of acoustic and LM
probabilities.<br>

I'm not sure what you mean by "accumulated", but when the same ngram
occurs multiple times the corresponding posterior-weighted counts are
added.<br>
