Recruiting studies
- NCT06856785Recruiting
Treating Voice Problems Without Surgery in Adults
This trial tests a therapy for adults with voice changes not caused by a physical illness. It looks at whether voice therapy can help people who have trouble with their voice but whose vocal cords are essentially healthy.
SohagAges 15–60 - NCT06100601Recruiting
Nervous System and Voice Disorder Study
This study looks at how the autonomic nervous system (the part that controls things like heart rate and sweat) might be linked to functional dysphonia, a voice problem with no clear physical cause. If you have this voice disorder and meet the health and lifestyle criteria, your participation could help improve understanding of the condition.
Ghent, East-FlandersAges 18–60 - NCT06524193Recruiting
Comparing in-person vs online voice therapy for voice strain
This study compares the effectiveness of face-to-face voice therapy versus online voice therapy for muscle tension dysphonia (a voice disorder from throat muscle strain). It tests whether doing therapy via video call works just as well as in-person sessions.
Hong KongAges 18 years+ - NCT06779799Recruiting
Study of vocal cord lesions in autoimmune disease patients
This study examines vocal cord lesions, like 'bamboo' nodes, that cause voice changes (dysphonia) in people with autoimmune diseases such as lupus or rheumatoid arthritis. It aims to better understand and characterize these lesions to improve diagnosis and treatment.
BrestAges 18 years+ - NCT07145086RecruitingPhase 3
Vibration therapy for voice problems
This trial tests if gentle vibration applied to the neck can help people with voice problems caused by muscle strain (hyperfunctional dysphonia). If you have a strained voice without vocal cord lesions and may benefit from voice therapy, this study could help you.
Fort Worth, TexasAges 18 years+ - NCT07176988Recruiting
Voice therapy study for certain voice problems
This study tests a behavioral voice therapy approach for people with voice issues caused by muscle tension or benign vocal fold lesions. It aims to improve communication and requires participants to attend sessions and practice with a smartphone.
Atlanta, GeorgiaAges 16–65 - NCT06152627Recruiting
Voice Therapy for Muscle Tension Dysphonia
This study tests a new way of doing voice therapy for people with muscle tension dysphonia — a condition where the muscles around the voice box are too tight, making it hard to speak clearly. The goal is to see if this structured approach helps improve voice function.
Atlanta, GeorgiaAges 14 years+ - NCT03042962Recruiting
Brain imaging study of focal dystonia and related conditions
This trial uses brain scans to understand how brain networks work in people with focal dystonia, and to compare with family members and healthy volunteers. It may help researchers better understand what goes wrong in the brain and guide future treatments.
Boston, MassachusettsAges 21–80 - NCT03042975Recruiting
Study brain and voice genetics in people with voice movement disorders
This study looks at how genetics and brain patterns are connected to laryngeal dystonia and voice tremor, including people with certain types of voice disorders. You may be asked to do imaging and voice-related assessments to help researchers understand what’s causing these symptoms.
Boston, MassachusettsAges Any age - NCT04014413Recruiting
Fecal transplant for gut and immune-related conditions
This trial studies whether fecal microbiota transplantation (FMT)—a medical procedure using stool from a screened donor to restore gut bacteria—can improve safety and outcomes for people with certain bowel, immune, and metabolic conditions. It may help if your symptoms are thought to be related to an unhealthy gut microbiome, though eligibility is broad and depends on specific safety factors.
Hong Kong, ShatinAges Any age - NCT05150093Recruiting
Deep brain stimulation for voice tremor or dystonia
This trial studies deep brain stimulation (a surgically placed device that sends electrical signals) to reduce voice tremor or laryngeal dystonia. You may be considered if your symptoms are persistent despite medication and you can complete the study tasks and pre-surgery testing.
Boston, MassachusettsAges 18–80 - NCT05150106Recruiting
Study brain and voice patterns in laryngeal dystonia
This study looks at how the brain and voice system work in people with laryngeal dystonia or voice tremor, and compares them with healthy volunteers. The goal is to better describe different “types” (phenotypes) so future care can be more targeted.
Boston, MassachusettsAges 18–80 - NCT05216770RecruitingEarly Phase 1
Brain-scan study of voice dystonia and tremor
This early study uses brain and voice-related testing to better understand what is happening in the brain in people with laryngeal dystonia or voice tremor. The results may help scientists learn more about these conditions and how they differ from healthy voices.
Boston, MassachusettsAges 18–80 - NCT05317390Recruiting
Tests an AI tool to diagnose isolated dystonia
This trial checks whether an AI (software) called DystoniaNet can accurately identify isolated dystonia using information from your evaluation, and compares its results to standard diagnosis. If you have focal, segmental, or generalized dystonia, this study may help improve faster and more accurate diagnosis in the future.
Boston, MassachusettsAges Any age - NCT05506085Recruiting
Brain stimulator study for voice spasms with tremor
This trial studies a brain stimulation approach for a specific voice disorder that can include tremor. It aims to better understand how well the treatment works and how to use it more effectively while carefully checking safety with awake procedures.
Indianapolis, IndianaAges 18–70 - NCT05970562RecruitingEarly Phase 1
Voice therapy plus biofeedback for vocal overuse problems
This early-phase study tests a mix of voice therapy and “biofeedback” (real-time feedback to help you change how you use your voice) for people with vocal overuse symptoms. It may help improve voice quality by targeting muscle tension and strain that happen when the voice is overworked.
Boston, MassachusettsAges 18–65 - NCT06999577RecruitingPhase 4
The Mechanism Versus PPI Trial for throat reflux
This study tests how well omeprazole (a common acid-blocking medicine) works for people with laryngopharyngeal reflux (LPR), a condition where stomach acid irritates the throat. If you have had throat symptoms for more than 8 weeks and are already scheduled for an endoscopy with acid monitoring, you may qualify to see if this medicine helps more than a placebo.

Common questions
- Are there clinical trials for dysphonia?
- Yes. Clin2 currently lists 17 recruiting dysphonia studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a dysphonia trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a dysphonia trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
