Project Grant R21DC024031
- The National Institute on Deafness and Other Communication Disorders awarded Northeastern University $197,000 on May 1, 2026, under the Research Related to Deafness and Communication Disorders program (CFDA 93.173) to investigate clinical phenotypes of feedback and feedforward control in adults who stutter. The research tests two hypotheses: that distinct stuttering behaviors are associated with behavioral and neural correlates of feedback and feedforward control (Aim 1), and that distinct...
- The National Institute on Deafness and Other Communication Disorders awarded Purdue University $504,483 on September 1, 2026, under the Research Related to Deafness and Communication Disorders program (CFDA 93.173) to characterize developmental trajectories that predict persistence or recovery from speech sound disorder in children. The project recruits a large cohort of children with diverse speech abilities at age four and follows them annually through age seven to identify predictive...
- The National Institute on Deafness and Other Communication Disorders awarded Michigan State University $1,295,404 under Research Related to Deafness and Communication Disorders (CFDA 93.173) on September 9, 2025. This project grant (R01DC021946) funds a multifactorial, longitudinal investigation of risk and protective factors underlying the development of stuttering's adverse impact on children, with performance in East Lansing, Michigan, through August 31, 2030. The research employs a...
- The National Institute on Deafness and Other Communication Disorders awarded the Regents of the University of Michigan $648,923 on July 20, 2026, under the Research Related to Deafness and Communication Disorders program (CFDA 93.173) to develop and test a digital rhythm-based intervention game for children who stutter. The project, identified as R01DC023753, addresses stuttering treatment limitations by leveraging neuroscientific understanding of basal ganglia thalamocortical network...
- The National Institute on Deafness and Other Communication Disorders awarded Purdue University $450,000 on August 15, 2026, under the Research Related to Deafness and Communication Disorders program (CFDA 93.173) to develop a cross-species knowledgebase for precision auditory neuroscience and audiology. Purdue will build a community-driven, standards-based knowledgebase that establishes data standards and ontologies to harmonize cross-species hearing research data and create predictive models...
- The National Institute on Deafness and Other Communication Disorders awarded Purdue University $159,116 on September 30, 2025, under the Research Related to Deafness and Communication Disorders program (CFDA 93.173) to investigate patterns of speech perception and production abilities among late-talking children and whether these skills predict later phonological development and speech-sound disorder. The project examines a large cohort of both late talkers and typical talkers at ages three...
- The National Institute on Deafness and Other Communication Disorders awarded the University of Wyoming $174,742 on August 10, 2026, under the Research Related to Deafness and Communication Disorders program (CFDA 93.173) to evaluate the efficacy of remote, artificial intelligence-based articulatory cueing for dysarthria secondary to Parkinson's disease. The project develops and tests an AI-driven individualized speech cueing tool delivered through a remote platform using consumer-grade...
- The National Institute on Deafness and Other Communication Disorders awarded the Trustees of Indiana University $618,089 on February 1, 2026, under the Research Related to Deafness and Communication Disorders program (CFDA 93.173) to investigate exercise-induced laryngeal obstruction through real-time pathophysiological measurement. The project, titled "Respiratory and Real-Time Laryngeal Dynamics in Exercise-Induced Paradoxical Vocal Fold Motion," develops a novel wireless...
- The National Institute on Deafness and Other Communication Disorders awarded the University of Wisconsin–Madison $305,152 on September 30, 2025, under the Research Related to Deafness and Communication Disorders program (CFDA 93.173) to investigate the neurocomputational mechanisms underlying speech sensorimotor adaptation. The funded research will test whether adaptation in speech involves two distinct learning processes—a fast process that learns quickly from error but retains less, and a slow...
- The National Institute on Deafness and Other Communication Disorders awarded the University of Pittsburgh $664,448 on September 1, 2026, under the Research Related to Deafness and Communication Disorders program (CFDA 93.173). The award funds investigation of how heterogeneous neural responses in auditory cortex and secondary motor cortex contribute to auditory learning and perception. The project combines large-scale neural recordings with optogenetic manipulations to examine how local auditory...
The National Institute on Deafness and Other Communication Disorders awarded Purdue University $210,050 on August 4, 2026, under the Research Related to Deafness and Communication Disorders program (CFDA 93.173) to develop and validate a novel device that reduces stuttering through machine learning–controlled altered auditory feedback modulated by the user's real-time brain activity. The research combines experimental and engineering work to establish the foundation for a device that delivers optimized delayed and frequency-altered auditory feedback only when stuttering moments are predicted to occur. Current commercial devices rely on always-on feedback, which users report loses effectiveness over time and is difficult to tolerate. The proposed system will use electroencephalographic (EEG) data to train and validate machine learning classifiers that predict upcoming stuttering moments, enabling the device to activate targeted feedback at critical junctures. The goal is to achieve approximately 90 percent fluency enhancement comparable to choral speech, the current gold standard. Performance occurs at Purdue University's West Lafayette, Indiana campus from August 4, 2026, through June 30, 2029. The award is classified as a Project Grant and represents an R21 mechanism, which supports exploratory and developmental research to establish feasibility and gather preliminary data for larger subsequent investigations.
