Cross-modal Interactions in Visual as Opposed to Auditory Perception of Vowels
Proceedings of Fonetik 2006, the XIXth Swedish Phonetics Conference, Lund, June 7-9, 2006. Working Papers 52, Department of Linguistics, Lund University: 137-140.
This paper describes two perception experiments with vowels in monosyllabic utterances presented auditorily, visually and bimodally with incongruent cues to openness and/or roundedness. In the first, the subjects had to tell what they heard; in the second what they saw. The results show that the same stimuli evoke a visual percept that may be influenced by audition and may be different from the auditory percept that may be influenced by vision. In both cases, the strength of the influence of the unattended modality showed between-feature variation reflecting the reliability of the information.
