GhentAges 4–12 - NCT06181149Recruiting
Stuttering and how the brain predicts speech sounds
This study uses brain imaging and stimulation to understand how people who stutter process speech sounds. It may help explain why stuttering happens and guide future treatments.
Tempe, ArizonaAges 3 years+ - NCT05988515Recruiting

Columbus, OhioAges 18–70 - NCT07426276Enrolling by invitation
Parent training plus speech therapy for speech development disorder
This study tests whether combining parent training with speech therapy helps children with speech development disorder more than speech therapy alone. It is for children aged 3 to 5 who have been diagnosed with a developmental language disorder.
Messina, MessinaAges 3–5 - NCT06512168Recruiting
Measuring aided language development in children

Orlando, FloridaAges 3.5 years–5 years - NCT05929859RecruitingPhase 1/Phase 2
Speech therapy for sounds r and s in kids
This early-stage trial tests an intensive speech-therapy approach to help kids who have trouble saying the sounds “r” and/or “s.” It may help improve how clearly your child’s speech sounds and how confidently they speak.
Syracuse, New YorkAges 9–17 - NCT04620343Recruiting
Study of breathing treatment for EILO during exercise
This trial tests a treatment approach for exercise-related breathing difficulty called EILO. It aims to help people whose breathing problems show up during peak exercise and who want ongoing follow-up.
Bergen, VestlandAges 12 years+ - NCT06164717Recruiting
Study of how the brain controls speech
This trial tests how people adapt their speech when they hear their own voice altered. It may help understand speech control in healthy people and those with Deep Brain Stimulation (DBS) for essential tremor or Parkinson's disease.
Seattle, WashingtonAges 4 years+ - NCT07815249Recruiting
Speech therapy for children with rare genetic conditions and speech apraxia
This trial tests a speech therapy program for children with rare genetic conditions who also have childhood apraxia of speech, a disorder where the brain has trouble planning the movements needed for speech. The therapy is intensive—three sessions a week for four weeks—and may help improve your child's ability to speak clearly.
Melbourne, VictoriaAges 3–16 - NCT05609084Recruiting

East Lansing, MichiganAges 50 years+ - NCT06381713Recruiting
Speech therapy for children with cleft palate
This study compares two types of speech therapy for children with cleft palate. It looks at how well each type works and how much it costs, to help find the best way to improve your child's speech.
GhentAges 4–12 - NCT07397975Recruiting
Using speech to predict relapse in psychosis
This study uses speech recordings from a smartphone app to see if changes in the way you talk can predict when someone might have a relapse of psychosis. It is for people who are currently stable or for healthy volunteers to compare.
KlecanyAges 18–65 - NCT06895395Recruiting
Speech therapy for kids with cleft palate
This study compares different types of speech therapy for children born with a cleft palate who have developed certain speech errors. The goal is to learn which therapy works best from the perspective of the child, their family, and the speech therapist.

- 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.
