Is this trial a fit for you?
✓Likely a good fit
Adults with a DSM-5 diagnosed current-use disorder for a primary addiction (substance or behavioral) who report regular craving and have used the addiction on at least 10 days in the last 30 days.
✕Probably not a fit
Individuals without a primary addiction meeting DSM-5 criteria or those who do not experience detectable craving may not benefit.

What this trial studies
This observational study will explore whether vocal features can serve as biomarkers for craving in people with substance or behavioral addictions. Participants will complete a cue-reactivity protocol involving different voice tasks and then provide Ecological Momentary Assessments via smartphones. The study aims to identify associations between craving episodes and voice-derived data collected passively or with minimal effort from participants. Findings could lead to a noninvasive way to monitor craving without relying solely on self-report. The lead site is at the University of Bordeaux in France.
Why it matters
Potential benefit: If successful, the approach could enable passive monitoring of craving to help guide treatment and support.
How similar studies have gone: Prior research supports links between behavioral biomarkers and craving, but vocal biomarkers in addiction remain exploratory and not yet established.
