We’re tracking 14 recruiting speech studies with a site in California, each written for real people, not researchers.
Recruiting studies in California
- 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 - 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+ - NCT05634356Recruiting
Study of how early speech learning changes with social input
This study looks at how infants learn speech sounds through everyday social interaction, like parent talk. It may help researchers understand what supports early speech development, including in babies with typical hearing and those with hearing loss or hearing devices.
Los Angeles, CaliforniaAges 7 months–2 years - NCT05489965Recruiting
Looking at voice outcomes in people using a TEP after laryngectomy
This study follows people who have had their voice box fully removed (total laryngectomy) and who use a TEP (a specific type of voice device). It aims to understand whether voice results differ between men and women.
La Jolla, CaliforniaAges 18 years+ - NCT07217366Enrolling by invitation
Speech-to-text tool for heart failure patients
This study tests a speech-to-text tool to help people with heart failure report their symptoms and health information more easily. It aims to see if using voice instead of typing can improve data collection.
Palo Alto, CaliforniaAges 18 years+ - NCT06812273Recruiting
Auditory training study for younger and older adults
This trial tests whether auditory training can improve how people process sounds. It compares outcomes between younger adults (18-30) and older adults (60-85) who have normal or near-normal hearing.
Riverside, CaliforniaAges 18–85 - NCT03698149Recruiting
Brain-signal training for hand and speech control after disability
This study tests whether recording brain signals can help people regain better control of movements in the arms and help with speech. It may be an option for people with significant disability from certain nerve and brain conditions who can safely take part in brain-monitoring procedures.
San Francisco, CaliforniaAges 21 years+ - NCT06094205Recruiting
BrainGate2 speech study for people with tetraplegia
This study tests a brain-computer interface to help people with severe paralysis communicate by decoding attempted speech or movements. It may offer a new way to interact with devices using only brain signals.
Sacramento, CaliforniaAges 18–80 - NCT06152211Recruiting
Music therapy for aging and Alzheimer's disease
This trial tests if music-based activities can help older adults with or without Alzheimer's. You'll attend weekly music sessions and be assessed over time.
Los Angeles, CaliforniaAges 65 years+ - NCT06580847Recruiting
Choir for older adults with untreated hearing loss
This trial tests whether joining a choir helps older adults with untreated hearing loss. If you have mild-to-moderate hearing loss and do not use hearing aids, this study may be a good fit for you.
Los Angeles, CaliforniaAges 60 years+ - NCT06823024Enrolling by invitation
Using speech patterns to predict treatment response in depression, PTSD, or bipolar disorder
This study tests if a computer algorithm can analyze your speech to predict how well you will respond to treatments like TMS or Spravato. It aims to create a simple tool that helps doctors choose the right treatment for you.
Sunnyvale, CaliforniaAges 18–68 - 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.

What taking part in a speech study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.

Common questions
- Are there speech clinical trials in California?
- Yes. We're currently tracking 14 recruiting speech studies with a site in California, each rewritten in plain language so you can see what it's testing and who it's for.
- How do I find out if I qualify for a speech study in California?
- Each study lists its eligibility rules — age, diagnosis, prior treatments. On every trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Do I have to live in California to take part?
- Not necessarily. These studies have a site in California, but eligibility is about your health, not your address — some people travel to take part, and a few studies reimburse travel. The study team can tell you what's required.
- Does it cost anything to join a speech trial?
- Using Clin2 is always free. Many trials cover the study treatment and related visits; some reimburse travel. The study team explains exactly what's covered before you decide.
Not the right time?
New speech studies open in California regularly. Set up a health profile and we’ll quietly watch for studies that fit you and email you when one opens.
Clin2 helps you find and understand clinical trials and does not provide medical advice. Study data comes from ClinicalTrials.gov. Talk with your doctor about whether a specific trial is right for you.
