Here the "Uncanny Valley", where falling just short of perfection in creating synthetic humans exacts a large negative reaction, is explored with talking head animations focusing on naturalness in speech, face model and face motion. We discuss possible techniques to manipulate naturalness for each of these aspects. Outcomes of this method will provide insights for the choice of the degree of realism or naturalness required for various talking heads.
