Benefits of a Virtual Language Tutor

Language is multimodal, and in second language learning, visual signals may in many contexts be more important than verbal signals. It has been shown that subjects listening to a foreign language often incorporate visual information to a greater extent than do subjects listening to their own language. The talking head can take advantage of this. Ville can for example give visual cues to signal prominence, emotion, encouragement, affirmation, confirmation and turntaking.
Compared to a human language teacher, he will of course appear vastly inferior in most respects, but he also have some benefits over the human teacher:
