Substance abuse, a prevalent concern in post-acute care (PAC) and long-term care (LTC) settings, can significantly alter speech patterns and vocal characteristics. voice biomarkers analysis offers a method for detecting subtle changes in voice associated with substance use and withdrawal. GIA®, powered by digitalhumanOS™, offers a method for identifying individuals at risk for substance abuse based on their vocal characteristics. Early detection can lead to timely intervention and support. Let's explore how voice biomarkers can be utilized to screen for substance abuse in PAC settings.

The Impact of Substance Abuse on Voice

Substance use can lead to changes in speech rate, articulation, and vocal intensity. Withdrawal symptoms may also affect vocal cord function.

Identifying Vocal Biomarkers of Substance Abuse with GIA®

GIA® analyzes parameters such as speech rate, pause duration, and vocal tremor to identify patterns associated with substance abuse.
