I trying to get indecies for words subtituted, inserted and deleted I found the alignments.alignment_chunk and seems not bad but it always give index depand on hypo text.
for example
if the referance is :
" I trying to get indecies for words subtituted, inserted and deleted I found the alignments.alignment_chunk and seems not bad but it "
and the hypo is: "for words"

the number of word deleted is right but indecies of deletion depand on length of hypo, I mean word in index 7 in refance was deleted and I didnt get it in alignment_chunk.
Do you have some way to get the all indecies in the sentece were deleted?
