general help

Hi, Crouching tigers & hidden dragons:

I am using a word based trigram (GT backoff) for an application, and
trying to make futher improvement. I tried to use class based, but
seemed not so good as word based. Higher gram (4gram) seems also worse
than 3gram. The WER (word error rate) i got now is about 8-10%, it seems
that there is still some room for improvement. Anyone got good ideas --
within ngram. Thanks in advance.
