When they were by the house of Micah, they knew the voice of the young man the Levite: and they turned in thither, and said unto him, Who brought thee hither? and what makest thou in this place? and what hast thou here? They knew the voice of the young man - They knew, by his dialect or mode of pronunciation, that he was not an Ephraimite. We have already seen (Judges 12:6 (note)) that the Ephraimites could not pronounce certain letters.
