- Auditory masking effects on speech fluency in aphasia and apraxia of speech
- We are currently recruiting stroke survivors with speech or language difficulties (i.e. aphasia) to participate in a research study investigating the effects of listening to noise on speech.
- You or someone you know may be eligible if you have experienced an ischemic stroke at least six weeks ago and have speech or language problems resulting from the stroke.
- This research study, “Auditory masking effects on speech fluency in aphasia and apraxia of speech” (IRB #10-0503), has been approved by the UNC Biomedical Institutional Review Board.

Dr. Jacks’s training background includes doctoral work in communication sciences and disorders at The University of Texas at Austin, postdoctoral research in behavioral neuroimaging at The University of Texas Health Science Center at San Antonio, and clinical experience in long term acute care and outpatient rehabilitation settings. His research focuses on understanding the link between neuropathology and behavioral manifestations of neuromotor speech disorders. Experimental methodologies used in this work include neuroimaging techniques (e.g. functional magnetic resonance imaging [fMRI]), acoustic and perceptual analysis of speech, testing of categorical perception abilities, and experimental perturbation of speech production and perception (e.g. bite block speech, pitch and formant shifting). By studying the operational characteristics of motor control in normal and disordered speech, Dr. Jacks hopes to contribute knowledge that enables better prediction of speech abilities in individuals with neurological injury or disease and development of more effective treatments for persons with motor speech disorders.
