• The Food Naturalness Index (FNI) accurately predicts perceived naturalness. Perceived is strongly associated with the Index. FNI proposed as a tool for regulating use of naturalness claims. For many consumers, it important that food products be natural. property food, but in present study, we demonstrate an objectively defined high degree accuracy. A sample 179 participants ranked 28 snacks, ...

This paper examines whether observed phenomena in energy declination can be used to improve the naturalness of synthetic speech. In two production experiments different aspects of intensity fall-off within utterances are analysed including degree of stress, phrase length, phrase boundaries. Energy manipulation was carried out using diphone synthesis as a basis for generating stimuli for percept...

In this experiment we examine the uncanny valley effect as a guide, albeit incomplete, to designing engaging humanlike interfaces. In this effect falling just short of perfection in creating synthetic humans elicits a pronounced negative reaction and here this is explored with talking head animations focusing on naturalness in speech, appearance and face motion. We implemented a set of techniqu...
