AI app to detect drunk drivers through Cantonese speech analysis in the works

Hong Kong Metropolitan University (HKMU) researchers are developing the world's first AI application designed to detect drunk drivers by analyzing Cantonese speech in real-time. This self-assessment tool aims to enhance road safety by helping individuals determine if they are fit to drive after consuming alcohol. The project, funded by a HK$3.4 million grant from the Smart Traffic Fund, will involve collecting over 1,000 minutes of Cantonese speech samples from approximately 100 participants. Beyond detecting intoxication, the app may also identify language abnormalities associated with medication or fatigue. The research is ongoing, with the goal of creating a comprehensive post-drinking speech database.
