Abstract
In this paper we report the results of a user study evaluating talking heads in the smart home domain. Three noncommercial talking head components are linked to two freely available speech synthesis systems, resulting in six different combinations. The influence of head and voice components on overall quality is analyzed as well as the correlation between them. Three different ways to assess overall quality are presented. It is shown that these three are consistent in their results. Another important result is that in this design speech and visual quality are independent of each other. Furthermore, a linear combination of both quality aspects models overall quality of talking heads to a good degree.
