Lookahead model only recognizes words from word list

[dpny518]

I was able to get the lookahead model working, but it seems to recognize only words from the wordlist, for example, lets say I pass "one two three" and the person speaks my name is alpha and I can count to one two three, it produces wrong results because the words prior to one two three are also recognized as one two three. I wanted to implement a phrase hint system for example, perform normal asr but put more weight on words passed through a list.

I might need to change G.fst construction in sources for that, will look on it a bit later.

@nshmyrev have you been able to test and repeat this? Where there are a lot of false positives for the words in the lookahead graph

[nshmyrev]

@yondu22 sure, its kind of reasonable. Add [unk] to the word list for now, it will be better. I'll be implementing proper spotting soon, it just requires some work on my side.

thank you [unk] did help a lot, still a lot of false positives but not as much as before
