Hi @safas - that does seem odd.
If you’ve closely followed the instructions then it should only return words from your vocabulary file (as per the video where you see it interpret things I say, when talking to the viewer at the end, as the closest fitting words from the vocab only (which are completely not the actual words I’ve said))
I expect you’ve checked carefully already but is it possible that at some stage you’ve either pulled in a different vocabulary file or somehow pointed the script at a different LM, words.arpa file or trie?
