Vocal Biomarkers of Craving

Addiction is a psychiatric disorder associated with craving, an unwanted, intense and persistent desire to use the substance/addictive behavior, leading to frequent relapses. Craving is fluctuating, influenced by internal factors or environmental context, and can be evaluated only by self-report which can be burdensome. It has been shown that craving predicts relapse, making it a major treatment target in addiction. Identify biomarkers of craving could enable to detect craving in a passive way (without major effort from individuals to report it) and would be a major improvement. The goal of this observational study is to explore if voice could be a biomarker of craving in adults with substance or behavioral addictions. The main question it aims to answer is: • Is there voice features associated with craving episodes in addiction ? Participants will undergo a cue-reactivity protocol with different voice tasks, and then answer Ecological Momentary Assessment (EMA) questionnaires on smartphone, with some of the questionnaires recorded out loud with the smartphone's microphone.
