Keyword spotting using Word lattice

Hi,
I am able to use the pocketsphinx kws with some success. However, I wanted to explore keyword spotting using word posterior on word lattice. So I have generated the lattice. Does Sphinx have a tool that can process the lattice for word posterior probability for a given word? Are there any other tool kits that does it? Any suggestion and pointers are welcome

Thanks
Ram

No

You can use lattice-tool from srilm for example. You dump pocketsphinx lattice in HTK format and load it into srilm
