The Prechter Program has entered an exciting new era of the PRIORI project! Since 2013, Drs. Emily Mower Provost and Melvin McInnis have worked tirelessly to develop a smartphone application and data pipeline to predict mood state changes based on variations in speech during phone calls and clinical interviews.
The newest era of the PRIORI project, PRIORI Ambient, is being conducted with the National Institutes of Health (NIH) and is built on what Prechter Program researchers learned from earlier, smaller iterations of the PRIORI project. In the previous study, we used the PRIORI app to collect voice data and discovered that we could predict how severe a person’s mood symptoms might be. For instance, our predictions matched very closely with how the participants said they were feeling each day in terms of depression. Additionally, the information we got from analyzing their speech and the emotions they reported feeling contributed to our prediction model in similar ways.
Our goal is to find ways to spot these changes in mood as they happen, without making people do anything extra or different. We’re inspired by the idea that you can often detect changes in someone’s mood through the way they sound, so we’re developing technology that listens to people’s voices passively, in real time, and picks up on emotional changes.
Thanks to funding from the National Institutes of Health (NIH), Drs. Sarah Sperry and Emily Mower Provost are working to study how 160 people talk in their daily lives over the next five years using smartphones equipped with a new version of our proprietary PRIORI (Predicting Individual Outcomes for Rapid Intervention) app. The newest version of the app captures 30 second snapshots of speech every 15 minutes as individuals go about their normal daily lives.
Participants in this study will also tell us how they’re feeling, and we’ll have clinical information about their mental health. We’re using advanced AI to analyze the emotions in their voices. Our team of researchers and research technicians are trying to figure out how these emotional clues, along with the participants’ own reports of their feelings, can help us understand the severity of their mood swings, whether they’re feeling manic or depressed.
This will allow us to better build a framework that can detect whether anomalies (changes) in speech are meaningful in the moment.
The long-term goal of this project is to provide innovative AI tools that people with bipolar disorder can use to help manage their mental health and improve outcomes.
