Sensors in smartphones may be able to detect how drunk a person is based on changes in their voice, according to a small study.

Following experiments involving 18 adults aged 21 and above, scientists said they were able to predict a person’s level of intoxication with 98% accuracy based on an analysis of their voice patterns.
