Feeling And Speaking: The Role Of Sensory Feedback In Speech, Francesca R. Marino

Senior Theses and Projects

Sensory feedback allows talkers to accurately control speech production, and auditory information is the predominant form of speech feedback. When this sensory stream is degraded, talkers have been shown to rely more heavily on somatosensory information. Furthermore, perceptual speech abilities are greatest when both auditory and visual feedback are available. In this study, we experimentally degraded auditory feedback using a cochlear implant simulation and somatosensory feedback using Orajel. Additionally, we placed a mirror in front of the talkers to introduce visual feedback. Participants were prompted to speak under a baseline, feedback degraded, and visual condition; audiovisual speech recordings were taken …
