Dear Xing, Actually, there does not exist any loudspeaker that could perfectly match the acoustic radiation pattern of the human mouth/head. The ideal solution would be to use a Head and Torso Simulator such as Brüel & Kjaer Type 4128D (see http://www.bksv.com/Products/TelecomAudioSolutions/HeadTorso/HeadandTorsoSimulatorHATSType4128D.aspx), if you can get one.
