Talking to your phone could detect diabetes, study finds
NCT ID NCT07421921
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether computer analysis of voice recordings can detect type 2 diabetes. Over 7,000 adults in the UK recorded themselves reading and answering questions online. A subset also provided blood samples to check accuracy. The goal is to see if voice biomarkers could become a simple, at-home screening tool for diabetes.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could lead to a simple, non-invasive voice-based screening tool for type 2 diabetes, making early detection easier and more accessible.
- What could go wrong
- This is an early-stage observational study, not a treatment trial. The voice analysis may not be accurate enough for real-world screening, and results may not apply to non-English speakers or people outside the UK.

Who is studied
The study population consists of a convenience sample of UK-based adults recruited through Prolific, an established online research platform widely used in the UK by researchers. This remote recruitment enables access to a geographically dispersed population across the UK, including individuals with known diabetes and those unaware of their metabolic health status. The online methodology reaches populations who may not engage with traditional healthcare screening, where NHS Health Check attendance is only 40.4%. The study recruits 10,000 participants for initial voice analysis, capturing diverse demographic representation to ensure model applicability across different population groups. A strategically selected subset of 1,000 participants will receive HbA1c validation testing. Existing participants from thymia's research database who consented to recontact are also eligible, having completed similar voice protocols, enriching the dataset whilst reducing participant burden.
