WARN: "main.c", line 826: Skipped utterance '<s> no </s>'

WARN: "mk_phone_list.c", line 178: Unable to lookup word '<s>' in the dictionary

Please let me know what is causing the problem.

As error says, you have problem with the word <s>. In your filler dictionary it is transcribed with lowercase phone sil, it must be uppercase phone SIL. Also, you do not need word SIL in the dict file, it must be the word <sil> in filler file instead.

Read tutorial carefully.
