Speech Amplification Devices for Parkinson Disease
This research study tests special amplification devices designed to help people with Parkinson disease or related conditions speak more clearly. The goal is to improve how well others can understand your speech.
East Lansing, MichiganAges 50 years+ - NCT05876910Enrolling by invitation
Study brain signals for stopping speech during epilepsy care
This study looks at how the brain helps stop ongoing speech. It may help researchers understand brain control during medication-resistant epilepsy surgery, using recordings from implanted electrodes.
San Francisco, CaliforniaAges 18–65 - NCT05435859Enrolling by invitation
Mapping the brain area for speech during surgery
This study uses tiny brain electrodes placed during surgery to better understand how a brain region helps with speech. The results may guide safer brain mapping during surgery for people with epilepsy or brain tumors.
San Francisco, CaliforniaAges 18–70 - NCT05014841Enrolling by invitation
Brain electrode study of speech across different languages
This study uses electrodes placed on the brain during surgery to understand how speech is represented in different languages. It may help doctors better map language areas and improve surgical planning for people having brain surgery.
San Francisco, CaliforniaAges 18–70 - NCT06491823Recruiting
Speech learning and memory study
This study tests how people learn and remember new speech patterns. You will participate in speech tasks while an MRI scans your brain activity.
New Haven, ConnecticutAges 18–40 - NCT06051006Recruiting
Testing Cochlear Implant Settings in Teens
This study tests a method to set cochlear implant sound levels using a small reflex in the ear. It may help doctors find the best sound settings for users aged 8-17.
ParisAges 8–17 - NCT04940000Recruiting
Remote video speech therapy check-ins for head and neck cancer
This trial tests whether video call speech therapy consultations can work well for people with head and neck (ORL) cancer who need speech/voice support during treatment. It may help you get care closer to home while still being guided by speech therapists.
ToulouseAges 18 years+ - NCT04997577Recruiting
Study of speech listening with high mental effort
This study tests how well you can understand speech when the task is mentally demanding. It may help researchers understand hearing and brain processing in older adults.
College Park, MarylandAges 65–85 - NCT04989309Enrolling by invitation
Study how each brain side helps you understand speech
This study looks at how the left and right sides of the brain help with speech understanding, using a safe brain-stimulation method called TMS. It may help researchers understand why some people struggle with speech and communication.
Storrs, ConnecticutAges 18 years+ - NCT06467292Recruiting
Speech Learning and Memory Study
This study looks at how people learn and remember speech movements. It may help explain how we improve speaking skills over time.
New Haven, ConnecticutAges 18–40 - NCT04290130Enrolling by invitation
Study brain signals during audiovisual speech in neurosurgery patients
This study measures brain activity to understand how your brain combines what you see and hear during speech. It may help scientists build better ways to understand and treat problems with speech processing.
Philadelphia, PennsylvaniaAges 21–65 - NCT05435989Recruiting
High-frequency hearing and speech testing for American English speakers
This study looks at how well people with normal hearing can hear high-pitched sounds and understand speech. If you speak American English and your hearing is normal within a specific sound range, you may be able to take part.
Champaign, IllinoisAges 19–50 - NCT06589570Recruiting
Titanium partial dentures and speech clarity study
This study tests how well a new type of metal partial denture made from titanium works for people missing multiple teeth. It looks at how the denture affects your speech and how easy it is to understand you.
CairoAges Any age - NCT06877897Enrolling by invitation
Ultrasound vs speech therapist for NG tube removal decision
This study is testing whether a simple ultrasound of the neck (called submental ultrasound) can help doctors decide when it's safe to remove a nasogastric (NG) tube, compared to a speech therapist's evaluation. If you have an NG tube that was placed due to a recent illness and are now recovering, this trial may help find a more reliable way to know when you can safely eat by mouth again.
Taipei, TaipeiAges 18 years+ - NCT06492252Recruiting
Speech learning and memory study
This study tests how well healthy adults learn and remember new speech patterns. You will say sounds or words, and we will measure how your brain controls speech.
New Haven, ConnecticutAges 18–40 - NCT07459803Recruiting
Speech motor skills study for neurotypical speakers and those with stuttering or dyslexia
This study looks at how different people control their speech muscles, comparing neurotypical speakers to adults who stutter or have dyslexia. It could help us understand why some people have trouble producing fluent speech.
Boston, MassachusettsAges 18–50 - NCT03313011Recruiting
Study brain patterns in progressive apraxia of speech
This study looks at brain changes in two types of progressive apraxia of speech, a condition that slowly worsens speech clarity. It may help researchers better understand the brain basis of your speech symptoms and how these types differ.
Rochester, MinnesotaAges 18 years+ - NCT03452202Recruiting
Brain stimulation to improve speech after stroke
This trial studies whether gentle brain stimulation (tDCS) can improve speech after a stroke. It focuses on people with stroke-related apraxia of speech while carefully checking hearing, brain function, and safety with devices or metal.
New York, New YorkAges 18–99 - NCT04432883Recruiting
Brain stimulation to improve speech after stroke aphasia
This trial tests whether targeted mild brain stimulation (tDCS) can improve speech therapy results for people with long-lasting (chronic) aphasia after a stroke. It may help strengthen naming and communication when added to standard speech-language treatment.
Albuquerque, New MexicoAges 25–85 - NCT05182892Recruiting
Reducing speech side effects from DBS using speech recordings
This study tests whether automated analysis of your speech can help reduce speech problems caused by deep brain stimulation (DBS) in Parkinson’s disease. It may help your team adjust DBS settings to improve how you speak while keeping Parkinson symptoms controlled.
PragueAges 18 years+ - NCT05365646Recruiting
In-ear device to test and improve speech clarity for fall risk
This study checks whether an in-ear device can enhance how clearly you speak, especially for people at risk of falling. You may do simple walking/standing tasks and use a study mobile app to help collect information.
Palo Alto, CaliforniaAges 55 years+ - NCT05468567Recruiting
Sound perception study for people with noise-related ear injury
This study looks at how people who have noise-related ear trauma perceive sounds, using a 3D (three-dimensional) sound setup. The results may help doctors better understand sound processing after acoustic injuries.

Common questions
- Are there clinical trials for speech?
- Yes. Clin2 currently lists 197 recruiting speech 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 speech 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 speech 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.
