There is something fundamentally wrong with this:

Shreveport is home to lots of people with southern drawls, and it's giving the police department fits.

The department's high-tech voice recognition system for routing non-emergency calls gets confused by drawls - what one police official calls "lazy mouth." Many callers have been misdirected to the wrong person or department.

So let me get this straight. The police department uses a machine to answer the telephone and route calls to the proper department, but it's the callers who are "lazy".
