Impact of High- and Low-Pass Acoustic Filtering on Audiovisual Speech Redundancy and Benefit in Children.

ABSTRACT:

Objectives

To investigate the influence of frequency-specific audibility on audiovisual benefit in children, this study examined the impact of high- and low-pass acoustic filtering on auditory-only and audiovisual word and sentence recognition in children with typical hearing. Previous studies show that visual speech provides greater access to consonant place of articulation than other consonant features and that low-pass filtering has a strong impact on perception on acoustic consonant place of articulation. This suggests visual speech may be particularly useful when acoustic speech is low-pass filtered because it provides complementary information about consonant place of articulation. Therefore, we hypothesized that audiovisual benefit would be greater for low-pass filtered word
