Making Words Disappear or Appear: A Neurocognitive and Behavioral Investigation of Effects of Speech Rate on Spoken Word Recognition

Making Words Disappear or Appear: A Neurocognitive and Behavioral Investigation of Effects of Speech Rate on Spoken Word Recognition

Understanding how humans comprehend speech is an unsolved and challenging problem, in part because factors such as different speakers, dialects, and speaking rates introduce a great deal of temporal and spectral variability into the speech signal. The focus of this research is on the influence of temporal context on perception of segments, syllables, and words. Results of the research may offer insights into treatment of disorders that involve disruption of speech rate (e.g., dysarthria, stuttering, Parkinson's disease, and aphasia), inform approaches to improve speech technology applications (e.g., enhanced automatic speech recognition, more natural sounding computer-generated speech), and lead to new discoveries related to brain mechanisms involved in understanding spoken language.
