Why we tend to roll back into our regional twangs after a few drinks

A new study has found out why we slip back to our hometown drawl after a few drinks.

According to the study, adapting or changing the accent you had growing up, whether you do so intentionally or not, takes cognitive power and motor control.

When you are drinking - or possibly sick, tired or cold - your body doesn't always act the way you want it to, reports the New York Daily News.

"We slur our words, and it's harder to maintain the motor coordination and control needed for effective fine motor execution needed for speech production," Amee Shah, director of Cleveland State University's Research Laboratory in Speech Acoustics and Perception, told NBC News.

In an inebriated state, your brain uses up all of its focus and power trying to get the basic tasks done, and controlling your speech does not rank at the top of the list, Shah said.

"We just don't have enough cognitive resources available for it," she said.
