Help on using lattice-to-kws-index

[raghav...@gmail.com]

Hi,
I am trying to build a KWS system. I have obtained the lattices and i have been trying to use the "lattice-to-kws-index" for obtaining the reverse index of the words in the lattice. One of the inputs to the program is the "utter.symtab". Where do i find theis file or do we have to create this file. If so how do we create this file.

Thanks.

IIRC,  that is just 1:1 mapping between utterance name and a number.  The index stores the id instead of the utterance name.
You can generate it any way you want (but I prefer having the utterances indexed sequentially), it will be needed only when processing the keyword search results.

Hi,
Thank you very much for the reply. So would it be fine that I index the Utterance file names sequentially maybe from 1 until say to the number of utterance files I have and store them into another file. Or am I missing out something here.

Thanks

Yes,  that should be fine - the format is similar  to what words.txt or phones.txt look like
