| Abstract: | The tone of a voice and its familiarity can greatly influence the level of attention that drivers pay to the voice of a navigation system. To determine what voice suits best a satellite navigation system, an interface that could read different navigation prompts with a voice configured by a user was created. Previous research has indicated what type of voice people prefer in such a context, but none of them allowed the user to create their own ideal voice. The present study addresses this question through a co-design experiment. 17 European nationals were asked to create the voice they would trust most in a navigation environment using the interface. Their voice selection and their responses from a short semi-structured interview were analyzed. The findings confirm some of the claims made in previous studies, such that people trust voices with a lower pitch more, but the expected bias towards female voices was not met. It was revealed that only pitch remained relatively constant between participants, and that accent preference relied heavily on what country the participant was from. Results indicate that to achieve good user satisfaction, navigation system makers need to provide an ample selection of voices, especially when it comes to their rate of speech. |
