Auditory feedback, the hearing of one’s own voice, plays an important role in the detection of speech errors and the regulation of speech production. The limited auditory cues available with a hearing loss can reduce the ability of individuals with hearing loss to use their auditory feedback. Hearing aids are a common assistive device that amplifies inaudible sounds. Hearing aids can also change auditory feedback through digital signal processing, such as frequency lowering. Frequency lowering moves high frequency information of an incoming auditory stimulus into a lower frequency region where audibility may be better. This can change how speech sounds …

It’S All About Context: Investigating The Effects Of Consonant And Vowel Environment On Vowel-Evoked Envelope Following Responses, Emma Bridgwater
Electronic Thesis and Dissertation Repository
The envelope following response (EFR) has proven useful for studying brainstem speech processing. Previous work, however, demonstrates that its amplitude varies across stimuli. This thesis investigates whether this variation is attributable to the consonant or vowel context of the stimulus, or some interaction of the two. Experiment 1 evoked EFRs in 30 participants using seven English vowels embedded in four CVC environments. A strong effect of vowel and a minor effect of consonant on EFR amplitude were found. In Experiment 2, 64 listeners heard four different tokens of one of four possible English vowels (16 participants/vowel), embedded in the same …
