      It's the expected result

      It's not a critical error, you can just ignore it.

      > ERROR: "f:\train\pocketsphinx\src\libpocketsphinx\lm_3g.c", line 1033: 'WEAN' is in LM unigrams but not in dictionary

      This one too. As you could understand from a error message the word is missing in the dictionary. To fix this situation you must open the dictionary with a text editor and add a word with a transcription there. Remember that words must be sorted. The dictionary is located at etc/an4.dic
