As a medical transcriptionist, my mom can decipher meaning from the mayhem of foreign doctors' dictations. And she can do it at the rate of over a hundred words a minute.
I heard: A sturdy turdist.
She heard: Respiratory therapist.
Aside from her other special power (inexhaustible dialogue), I'd say that's pretty impressive. I'd also say I wouldn't last long as a medical transcriptionist.
