To test that hypothesis, the researchers dug through an archive with conversations from 40 people raised in Columbus, Ohio. (Armstrong, from nearby Wapakoneta, had a similar accent.) People said "for a" 191 times. The researchers then measured the time it took those people to say "for a" versus just "for." Turns out, it doesn't take Ohioans much longer to say "for a" than it does "for," which indicates some blending of the words. Armstrong's frrr(uh) clocked in at 0.127 seconds, meaning it fell in that blended range.
