Please excuse the newbie question, but I have searched the archives and web for an answer, and have not been able to find one. I am running the following command:
echo "HUGE WIN OVER RUTGERS" > sentence.txt
lattice-tool -ppl sentence.txt -in-lattice footballPodcast.lat -read-htk -debug 2 -order 4
and am getting the folllowing results:
p( HUGE | <s> ) = 0 [ -inf ]
p( WIN | HUGE ...) = 0 [ -inf ]
p( OVER | WIN ...) = 0 [ -inf ]
p( RUTGERS | OVER ...) = 0 [ -inf ]
p( </s> | RUTGERS ...) = 0 [ -inf ]
Viterbi backtrace failed
1 sentences, 4 words, 0 OOVs
5 zeroprobs, logprob= 0 ppl= undefined ppl1= undefined
Anyone know what might be going on? The original utterance from which the lattice was built is 2 minutes long, containing much more speech than just the four word sentence I am testing on. Is that the problem?
Generally speaking, I am looking for a tool that can give me the highest probability location (along with the associated probability) of where a sequence of words was spoken in an audio file. I am using Sphinx 3.7 to generate lattices from the audio, and have been using various SRILM tools to examine these lattices. Is there a tool that does what I want, or will I need to make one?
Much thanks in advance!
