Janis, this replaces my comment posted yesterday. Today I hear what you described. Yesterday, though, I heard it pronounced "Nasú limtzó avodá!", which Pealim confirms is correct; I even heard his voice rising in tone at the end of each word, which today I don't hear for the verbs. Both times it's a man's voice. So either this is one of those "aural illusions", or Duo has 2 different recordings.
