Persian-speakers and Iranians have told The Washington Post that the accent in the American recording does not sound Iranian. 'The New York Times' pointed out that the United States-released audio includes no ambient noise of the kind that might be expected if the broadcast had come from on one of the speedboats.[1] The Navy Times wrote that the incident could have been caused by a locally famous heckler known as the "Filipino monkey", noting that the threatening voice sounds different from that of the Iranian officer.[15][16][17] Several media outlets reported that the Navy spliced the audio recording of the alleged Iranian threat onto to a videotape of the incident.[5][6][18][19][20][21]
