Language enables the acquisition of distinct sensorimotor memories for speech Open
Interactions between the context in which a sensorimotor skill is learned and the recall of that memory have been primarily studied in limb movements, but speech production requires movement, and many aspects of speech processing are influ…

Speech motor adaptation during synchronous and metronome-timed speech. Open
Sensorimotor integration during speech has been investigated by altering the sound of a speaker's voice in real time; in response, the speaker learns to change their production of speech sounds in order to compensate (adaptation). This lin…

Language Enables the Acquisition of Distinct Sensorimotor Memories for Speech Open
The role of context in the acquisition and recall of sensorimotor memories has been primarily studied in limb movements, but language use requires movement and context effects abound in the psycholinguistic literature. Here, in ecologicall…

Auditory and Somatosensory Development for Speech in Later Childhood Open
Purpose: This study collected measures of auditory-perceptual and oral somatosensory acuity in typically developing children and adolescents aged 9–15 years. We aimed to establish reference data that can be used as a point of comparison fo…

Immediate Cross Language Transfer of Novel Articulatory Plans for Speech in Bilinguals Open
Current models of second language (L2) acquisition focus on interactions with a first language (L1) at the level of speech sound targets. In multilinguals, the degree of interaction between the articulatory plans that guide speech in each …

Early auditory responses to speech sounds in Parkinson’s disease: preliminary data Open
Parkinson’s disease (PD), as a manifestation of basal ganglia dysfunction, is associated with a number of speech deficits, including reduced voice modulation and vocal output. Interestingly, previous work has shown that participants with P…

Visual feedback of the tongue influences speech adaptation to a physical modification of the oral cavity Open
Studies examining sensorimotor adaptation of speech to changing sensory conditions have demonstrated a central role for both auditory and somatosensory feedback in speech motor learning. The potential influence of visual feedback of oral a…

Toward an Index of Oral Somatosensory Acuity: Comparison of Three Measures in Adults Open
Purpose Somatosensory targets and feedback are instrumental in ensuring accurate speech production. Individuals differ in their ability to access and respond to somatosensory information, but there is no established standard for measuring …

Measures of oral somatosensory acuity in adults (Gritsyk et al., 2021) Open
Purpose: Somatosensory targets and feedback are instrumental in ensuring accurate speech production. Individuals differ in their ability to access and respond to somatosensory information, but there is no established standard for measuring…

Neural Correlates of Vocal Pitch Compensation in Individuals Who Stutter Open
Stuttering is a disorder that impacts the smooth flow of speech production and is associated with a deficit in sensorimotor integration. In a previous experiment, individuals who stutter were able to vocally compensate for pitch shifts in …

Exposure to auditory feedback delay while speaking induces perceptual habituation but does not mitigate the disruptive effect of delay on speech auditory-motor learning Open
Perceiving the sensory consequences of our actions with a delay alters the interpretation of these afferent signals and impacts motor learning. For reaching movements, delayed visual feedback of hand position reduces the rate and extent of…

Sensorimotor adaptation across the speech production workspace in response to a palatal perturbation Open
Talkers have been shown to adapt the production of multiple vowel sounds simultaneously in response to altered auditory feedback. The present study extends this work by exploring the adaptation of speech production to a physical alteration…
View article: Individual predictors of response to biofeedback training for second-language production
Individual predictors of response to biofeedback training for second-language production Open
While recent research suggests that visual biofeedback can facilitate speech production training in clinical populations and second language (L2) learners, individual learners' responsiveness to biofeedback is highly variable. This study i…

Adults who stutter and metronome synchronization: evidence for a nonspeech timing deficit Open
Speech timing deficits have been proposed as a causal factor in the disorder of stuttering. The question of whether individuals who stutter have deficits in nonspeech timing is one that has been revisited often, with conflicting results. H…

Can perceptual training alter the effect of visual biofeedback in speech-motor learning? Open
Recent work showing that a period of perceptual training can modulate the magnitude of speech-motor learning in a perturbed auditory feedback task could inform clinical interventions or second-language training strategies. The present stud…

Timing variability of sensorimotor integration during vocalization in individuals who stutter Open
Persistent developmental stuttering affects close to 1% of adults and is thought to be a problem of sensorimotor integration. Previous research has demonstrated that individuals who stutter respond differently to changes in their auditory …

Autophonic loudness perception in Parkinson's disease Open
The relationship between the intensity and loudness of self-generated (autophonic) speech remains invariant despite changes in auditory feedback, indicating that non-auditory processes contribute to this form of perception. The aim of the …

Please say what this word is—Vowel-extrinsic normalization in the sensorimotor control of speech. Open
The extent to which the adaptive nature of speech perception influences the acoustic targets underlying speech production is not well understood. For example, listeners can rapidly accommodate to talker-dependent phonetic properties-a proc…
