Future Cars May Prevent Drunk Driving Through Voice Recognition

ALCA group of scientists in Germany has developed the Alcohol Language Corpus (ALC), a database which may one day work as “a chattier version of the breathalyzer devices that prevent people from drunk driving now.” The database contains various drunken speech patterns collected through conversations with drunk people in the passenger seat of a car. The hope for this database is that it may one day work together with a high-tech device which will ask drivers a few questions before starting the car. If the driver’s responses or speech patterns seem to reflect that they are drunk, the car will not start.

The ALC database is still not perfect, however. In a recent study, it only correctly identified drunken speech 73% of the time. Still, this development could one day help to prevent many of the accidents caused by drunk drivers.
