Murray, Elizabeth S. Heller; Lupiani, Ashling A.; Kolin, Katharine R.; Segina, Roxanne K.; Stepp, Cara E. – Journal of Speech, Language, and Hearing Research, 2019
Purpose: This study details the intended and unintended consequences of pitch shifting with the commercially available Eventide Eclipse. Method: Ten vocally healthy participants (M = 22.0 years; 6 cisgender females, 4 cisgender males) produced a sustained /?/, creating an input signal. This input signal was processed in near real time by the…

Abur, Defne; Lupiani, Ashling A.; Hickox, Ann E.; Shinn-Cunningham, Barbara G.; Stepp, Cara E. – Journal of Speech, Language, and Hearing Research, 2018
Purpose: Reduced intensity is a hallmark of speech production in Parkinson's disease (PD). Previous work has examined the perception of intensity in PD to explain these speech deficits. This study reports loudness ratings of pure tones by individuals with PD and controls, all with normal thresholds for older adults. Method: Twenty individuals with…

Abur, Defne; Stepp, Cara E. – Journal of Speech, Language, and Hearing Research, 2020
Purpose: Given the role of auditory perception in voice production, studies have investigated whether impairments in auditory perception may underlie the noted disruptions in speech in Parkinson's disease (PD). Studies of loudness perception in PD show impairments in the perception of self-generated speech, but not external tones. Studies of pitch…

Murray, Elizabeth S. Heller; Mendoza, Joseph O.; Gill, Simone V.; Perkell, Joseph S.; Stepp, Cara E. – Journal of Speech, Language, and Hearing Research, 2016
Purpose: The purpose of this study was to determine the effects of biofeedback on control of nasalization in individuals with typical speech. Method: Forty-eight individuals with typical speech attempted to increase and decrease vowel nasalization. During training, stimuli consisted of consonant-vowel-consonant (CVC) tokens with the center vowels…

Kubert, Heather L.; Stepp, Cara E.; Zeitels, Steven M.; Gooey, John E.; Walsh, Michael J.; Prakash, S. R.; Hillman, Robert E.; Heaton, James T. – Journal of Communication Disorders, 2009
Three individuals with total laryngectomy were studied for their ability to control a hands-free electrolarynx (EL) using neck surface electromyography (EMG) for on/off and pitch modulation. The laryngectomy surgery of participants was modified to preserve neck strap musculature for EMG-based EL control (EMG-EL), with muscles on one side…

Goldstein, Ehab A.; Heaton, James T.; Stepp, Cara E.; Hillman, Robert E. – Journal of Speech, Language, and Hearing Research, 2007
Purpose: The "electrolarynx (EL)" is a widely used device for alaryngeal speech, but it requires manual operation and produces voice that typically has a constant fundamental frequency. An electromyographically controlled EL (EMG-EL) was designed and implemented to provide hands-free control with dynamic pitch modulation. Method: Three…
