Chicago, IllinoisAges birth–5 years - NCT05943834Recruiting
Voice testing to detect early memory and mood changes
This trial studies whether automated analysis of your voice and speech can help detect early signs of Alzheimer’s disease and mood (affective) problems. It may help identify changes sooner, using voice and questionnaire information from people who are cognitively healthy to very mildly affected.
NiceAges 50–100 - NCT05901233Enrolling by invitation
Remote brain stimulation and speech therapy for primary progressive aphasia
This study tests whether combining speech-language treatment with remotely supervised brain stimulation (a mild current to the scalp) can improve communication in people with primary progressive aphasia. You and a study partner would also join online training and regular video check-ins.
San Francisco, CaliforniaAges Any age - NCT05867173Recruiting
Testing how cochlear implant wiring affects hearing perception
This study looks at how the connection between cochlear implant electrodes and nerve signals changes what you hear. It may help scientists improve how cochlear implants “map” sounds to your brain.
Boston, MassachusettsAges 3 months+ - NCT05765110Recruiting
Tracking speech, movement, and thinking in Parkinson’s disease
This study looks at how people with Parkinson’s disease speak, move, and think to see whether these patterns can act like a “biomarker” (a measurable sign) of the disease. It also involves healthy volunteers to compare results.
PragueAges 30–75 - NCT05670496Recruiting
NIDCD medical data and sample collection for communication disorders
This study collects medical information and specimens to support research on problems with hearing, balance, taste, smell, voice, speech, and language. It may help you (or your child) get additional evaluation and follow-up through NIDCD, especially if your clinician thinks it could be useful.
Bethesda, MarylandAges 2–99 - NCT05635929Recruiting
Topical treatment to reduce mouth sores during or after radiation
This study tests a new cream/gel applied to the mouth to lower the chance of severe mouth sores in people receiving radiation for head and neck cancer. It also looks at how treatment affects quality of life using patient questionnaires.
Madrid, MadridAges 18 years+ - NCT05554692Enrolling by invitation
Study how aging and cochlear implants affect speech timing
This study looks at how the brain processes the timing of sounds and speech in people with cochlear implants and in people with typical hearing. It may help researchers understand what changes with age and how implant hearing works in the real world.
College Park, MarylandAges 18–85 - NCT05492266Recruiting
Breathing muscle training for nasal speech in children
This trial tests whether strengthening the muscles you use to breathe out can help children ages 5–17 who have too much nasal sound in their speech. If it works, it could reduce the need for surgery.
Pittsburgh, PennsylvaniaAges 5–17 - NCT05303649Recruiting
Theta burst brain stimulation for language problems after stroke
This study tests whether a type of brain stimulation guided by a brain scan (MRI) can improve speech and language (“aphasia”) after a stroke. It may help people who have trouble producing speech but can still understand others’ words.
Warsaw, Masovian VoivodeshipAges 18–75 - NCT05260307Recruiting
Improving hearing of multiple voices and speech understanding
This study tests ways to improve how people perceive space in sound and understand speech when many voices are talking at once. It may help adults with normal hearing or hearing loss better follow conversations in noisy, “overlapping voices” situations.
Boston, MassachusettsAges 18–80 - NCT05214092Enrolling by invitation
Study brain changes after surgery in teens and young adults
This study looks at how a brain area involved in hearing and language contributes to recovery after medically needed surgery. It may help doctors better understand post-op outcomes using language and hearing-related brain measurements.
Pittsburgh, PennsylvaniaAges 13–25 - NCT04696835Recruiting
Brain-light test with pediatric hearing aids
This study uses a special non-painful sensor test on the head (functional near-infrared spectroscopy, or fNIRS) to understand how young children’s brains respond while wearing hearing aids. It may help improve how hearing aids are adjusted for babies and toddlers with hearing differences.
LilleAges 3 months–1.5 years - NCT05066178Recruiting
Speech therapy for children with autism who speak very little
This study tests a speech treatment plan for children on the autism spectrum who currently speak very little. It aims to improve speech clarity and ability to repeat sounds, but only if the child’s home language environment and participation needs fit the study rules.
