Our Research Team


​​​​​Principal Investig​​ator

Kaylah Lalonde​ (she/her) is director of the Audiovisual Speech Processing Lab. Dr. Lalonde completed her Ph.D. in Speech and Hearing Sciences at Indiana University, followed by three years of postdoctoral training on the Auditory Neuroscience Training Grant and in Dr. Lynne Werner's Infant Hearing Lab at the University of Washington. ​​

At Boys Town National Research Hospital, Dr. Lalonde directs a project entitled “Factors Influencing Audiovisual Benefit in Children with Hearing Loss.” She also works collaboratively on a project entitled “Effects of Face Masks on Word Learning in Preschool Age Children.” Both projects are funded by the NIH National Institute on Deafness and Other Communication Disorders. Dr. Lalonde also directed completed projects entitled “Development of Audiovisual Speech Enhancement in Children" and “Effects of Hearing Aid Compression on Temporal Cues in Audiovisual Speech” that were funded through Centers for Biomedical Research Excellence Grants from the NIH. ​

Dr. Lalonde's research focuses on the development of audiovisual speech perception from infancy to adulthood and the effects of pediatric hearing loss on said development. Her work examines the contribution of auditory, visual, cognitive, linguistic, stimulus and task-related factors to performance on speech perception tasks—and thus to development in general. Her l​​ong-term goals are to form a unified account of the development of AV speech perception in noise and to improve outcomes for children with hearing loss by incorporating data about audiovisual speech perception into testing and intervention practices.​
