Summary

This study looked at whether changes in a person's voice can help detect opioid use in people being treated for opioid use disorder. Researchers collected voice samples from 41 patients and used machine learning to find patterns linked to opioid intoxication or withdrawal. The goal was to create a non-invasive, easy-to-use tool that could replace or supplement current methods like self-reports and drug tests.

Study facts

The number who actually took part.

Lead sponsor

A company

The lead sponsor is a pharmaceutical, biotech, or medical-device company.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

The study population is adult (18+) English-speaking men and women currently receiving OUD treatment at the Volpicelli Center, capable of consenting and completing the protocol, and free of severe psychiatric comorbidity or chronic speech-affecting conditions. Because participants are drawn from an active treatment population, they are by definition individuals already engaged in care for OUD rather than treatment-naïve or general-population samples - a relevant consideration when interpreting how the voice biomarker findings might generalize.
