I think what you mean is, "is there a way to give Kaldi at alignment time
the lexicon entry for these words?".
The easiest way to do this is to create a new "lang" directory that has a
larger lexicon, including the new words, and provide this directory to the
script that does the alignment..  You can use the prepare_lang.sh script
for this; just give it an input directory that has a larger lexicon.txt or
lexiconp.txt.  Make sure after you do this that the phones.txt files are
identical in the old and new directories, except possibly for extra
disambiguation symbols (#1, #2, etc.).
