A new study reveals that analyzing a few seconds of a person’s voice using AI can determine if they have Type 2 diabetes with up to 89% accuracy. This non-intrusive method has the potential to revolutionize diabetes screening by eliminating current detection barriers like time, cost, and travel.
Scientists at Klick Labs identify voice technology as a potential breakthrough in detecting Type 2 diabetes.
Identifying if someone has diabetes might soon be as simple as them uttering a few phrases into their smartphone, suggests a pioneering study from Klick Labs. This research merges voice recognition technology and artificial intelligence, marking a significant advancement in the field of diabetes identification.
The new study, published in Mayo Clinic Proceedings: Digital Health, outlines how scientists used six to 10 seconds of people’s voice, along with basic health data, including age, sex, height, and weight, to create an AI model that can distinguish whether that individual has Type 2 diabetes. The model has 89 percent accuracy for women and 86 percent for men.
For the study, Klick Labs researchers asked 267 people (diagnosed as either non- or Type 2 diabetic) to record a phrase into their smartphone six times daily for two weeks. From more than 18,000 recordings, scientists analyzed 14 acoustic features for differences between non-diabetic and Type 2 diabetic individuals.
“Our research highlights significant vocal variations between individuals with and without Type 2 diabetes and could transform how the medical community screens for diabetes,” said Jaycee Kaufman, first author of the paper and research scientist at Klick Labs. “Current methods of detection can require a lot of time, travel, and cost. Voice technology has the potential to remove these barriers entirely.”
A new clinical study by Klick Labs found that AI and 10 seconds of voice could change the way people screen for diabetes, offering better access and lower costs than current screening methods. The findings, published in Mayo Clinic Proceedings: Digital Health, reported 89 percent accuracy for women and 86 percent for men in predicting Type 2 diabetes from acoustic voice features.

The team at Klick Labs looked at a number of vocal features, like changes in pitch and intensity that can’t be perceived by the human ear. Using signal processing, scientists were able to detect changes in the voice caused by Type 2 diabetes. Surprisingly, those vocal changes manifested in different ways for males and females, Kaufman said.
A Potential New Screening Tool for Undiagnosed Diabetes
Almost one in two, or 240 million adults living with diabetes worldwide are unaware they have the condition and nearly 90 percent of diabetic cases are Type 2 diabetes, according to the International Diabetes Federation. The most frequently used diagnostic tests for prediabetes and Type 2 diabetes include the glycated hemoglobin (A1C), along with the fasting blood glucose (FBG) test and the OGTT–all of which include a trip to a healthcare provider for patients.
Yan Fossat, vice president of Klick Labs and principal investigator of this study, said Klick’s non-intrusive and accessible approach offers the potential to screen vast numbers of people and help identify the large percentage of undiagnosed people with Type 2 diabetes.
“Our research underscores the tremendous potential of voice technology in identifying Type 2 diabetes and other health conditions,” Fossat said. “Voice technology could revolutionize healthcare practices as an accessible and affordable digital screening tool.”
Fossat said next steps will be to replicate the study and expand their research using voice as a diagnostic in other areas such as prediabetes, women’s health, and hypertension.
