An apparatus for radio frequency testing of a wireless communication device (205) comprising an artificial head (100) and a spacer (203). The artificial head (100) includes a mouth (103) and an ear (105, 107), and the spacer (203) is positioned adjacent to the artificial head (100). The spacer (203) positions an audio output portion of the wireless communication device (205) adjacent to the ear (105, 107) of the artificial head (100), directs an audio input portion of the wireless communication device (205) toward the mouth (103) of the artificial head (100), and separates the audio input portion of the wireless communication device (205) from the mouth (103) of the artificial head (100).
