A quick, speech-based AI tool offers a new way to screen for a key indicator of the neurodegenerative disease.<\/h2>\n

Computer scientists at the University of Rochester<\/a> have developed an AI-powered, speech-based screening tool that can help people assess whether they are showing signs of Parkinson\u2019s disease, the fastest growing neurological disability in the world. A study<\/a> published in the journal npj Parkinson\u2019s Disease<\/em> introduces a web-based screening test that asks users to recite two pangrams\u2014short sentences using all 26 letters of the alphabet. Within seconds, the AI analyzes the voice recordings for subtle patterns linked to Parkinson\u2019s, with nearly 86 percent accuracy.<\/p>\n

Parkinson\u2019s disease is typically diagnosed by movement disorder specialists\u2014neurologists with specific training to evaluate complex motor symptoms\u2014using a combination of family history, neurological examinations, and brain imaging. While the study\u2019s authors emphasize that their AI-based tool is not a substitute for a clinical diagnosis, they see it as a fast, low-barrier, and accessible way to flag people, especially in remote areas, who might be living with the condition and encourage them to seek more thorough clinical evaluations.<\/p>\n

\u201cThere are huge swaths of the US and across the globe where access to specialized neurological care is limited,\u201d says Ehsan Hoque<\/a>, a professor in Rochester\u2019s Department of Computer Science<\/a> and co-director of the Rochester Human-Computer Interaction Laboratory<\/a>. \u201cWith users\u2019 consent, widely used speech-based interfaces like Amazon Alexa or Google Home could potentially help people identify if they need to seek further care.\u201d<\/p>\n

To train and validate the tool, the researchers collected data from more than 1,300 participants\u2014with and without Parkinson\u2019s\u2014across diverse environments, including home settings, clinical visits at the University of Rochester Medical Center<\/a>, and the InMotion Parkinson\u2019s disease care center in Ohio.<\/p>\n

Using the computer\u2019s microphone, users simply read aloud two sentences: \u201cThe quick brown fox jumps over the lazy dog. The dog wakes up and follows the fox into the forest, but again the quick brown fox jumps over the lazy dog.\u201d By leveraging the power of advanced semi-supervised speech models trained on millions of digital audio recordings to understand the characteristics of speech, the tool can glean enough vocal cues from those two short sentences to flag warning signs.<\/p>\n

\u201cThese large audio models are trained to understand how speech works; for example, the way someone with Parkinson\u2019s would utter sounds, pause, breathe, and inadvertently add features of unintelligibility is different in someone without Parkinson\u2019s,\u201d says Abdelrahman Abdelkader, a computer science master\u2019s degree<\/a> student in Hoque\u2019s lab and one of the two lead authors of the study. \u201cIf a person is saying the pangram that contains the full spectrum of the alphabetical variability and trails off at certain points, the model can tell if that\u2019s different from the typical representation and flag it.\u201d<\/p>\n

The tool was 85.7 percent accurate when tested, providing a strong indication of whether someone may have Parkinson\u2019s. But it is a multifaceted disease, and while some people demonstrate symptoms through speech, they can also display signs through motor tasks<\/a> or facial expressions<\/a>. Over the last decade, Hoque\u2019s lab<\/a> has pursued clever algorithms to combine multiple indicators<\/a> and produced state-of-the-art results.<\/p>\n

\u201cResearch shows that nearly 89 percent of people with Parkinson\u2019s have a deformity in their voice that can be indicative of the disease, making speech a strong starting point for digital screening,\u201d says Tariq Adnan, a computer science PhD student affiliated with Hoque\u2019s lab and another lead author of the study. \u201cBy combining this method with assessments of other symptoms, we aim to cover the majority of people through our accessible screening process.\u201d<\/p>\n

An interactive demo of the lab\u2019s three screening tests, including the speech test outlined in the paper, is available online<\/a>.<\/p>\n

The other authors of the paper include PhD students Md. Saiful Islam, who co-supervised the work with Hoque, Zipei Liu, Ekram Hossain, and Sooyong Park.<\/p>\n

The study was funded by the National Institute of Neurological Disorders and Stroke of the National Institutes of Health, the Gordon and Betty Moore Foundation, a Google Faculty Research Award, and a Google PhD Fellowship.<\/p>\n
