Speech-Driven Gestures:

Speech-Based Gesture Generation Using Deep Learning.

Speech-Driven Gestures

One of the unsolved problems in virtual agents’ research is the generation of high-fidelity body language and gestures that correspond to the utterances of the agent. 

Body language, including gestures, facial expressions, body posture, and movement, constitute a non-verbal portion of the communication process and are essential components of effective communication. In evolution, the spoken language comes as a secondary aid to body language.

The project is a collaboration between Dr. Pietroszek of Institute for IDEAS, Dr. Xiao in the Department of Computer Science, Dr. Guetl of the University of Graz in Austria.
