Reader’s Question:

A friend of mine got arrested in Palmdale, California because of DUI. He had a slurred speech according to the police report. Can a slurred speech be used as evidence in a DUI trial?

Just like the odor of alcohol on the breath of a person arrested for DUI, a very few police reports would fail to include an observation by the police officer that the person arrested exhibited “slurred speech” during the DUI arrest. The police officer usually expects to hear slurred speech in a person whom he/she suspects as intoxicated or driving under the influence, particularly after smelling alcohol on the breath. Also, it would be a psychological fact that we tend to “hear” what we expect to hear. And upon hearing a slurred speech, it supplies the police officer with a proof of his suspicions that the person was indeed intoxicated, and thus driving under the influence.

Assuming that the police officer was honest that your friend who was arrested for DUI in Palmdale, California had a slurred speech during the DUI arrest, there is little evidence that this is a symptom of intoxication. For example, impairment of speech, even when sober, is a common reaction to the stress, fear and nervousness that a police investigation would be expected to happen. Fatigue is also a well-known cause of having a slurred speech. A study of phonetician showed that even self-proclaimed experts are not good at estimating people’s alcohol levels by the way they talk.
