英文摘要	We evaluate a 3-D virtual talking head on non-native Mandarin speaker pronunciation learning under three language presentation conditions –audio only (AU), human face video (HF) and audio-visual animation of a three- dimensional talking head (3-D). An auto language tutor (ALT) configured with AU, HF and 3-D is developed as the computer-aided pronunciation training system. We apply both subjective and objective methods to study user acceptance of the 3-D talking head, user comparative impressions and pronunciation performance under different conditions. The subjective ratings show that the 3-D talking head achieved a high level of user acceptance, and both 3-D and HF were preferred to AU. The objective pronunciation learning improvements show that 3-D was more beneficial than AU with respect to blade-alveolar, blade-palatal, lingua-palatal, open-mouth, open-mouth(-i) and round-mouth. Learning with 3-D was better than learning with HF with respect to blade-alveolar, lingua- palatal and round-mouth, and the tones of falling-rising and falling. Learning with AU was better than learning with HF with respect to the falling-rising tone. Neither HF nor AU was superior to 3-D with respect to any of the initials, finals and tones.
