Re: [Kaldi-users] Improved arpa2fst

[Mailing l. u. f. U. C. a. U. <kal...@li...>]

Hi Giles,

This is great, I just tried the new version and it is much faster.
I compared  arpa2fst to ngramread from opengrm and arpa2fst is nearly two
times faster.
(Both were compiled with -O2 -g flags)

Thanks

Paul
