If you watch sports, whether the recent NBA finals or the ongoing World Cup matches, you may have noticed that the athletes aren’t the only ones putting on a show. The announcers seem to be playing a beautiful game of their own, capturing the excitement and play-by-play of the game in a unique blend of sentence structure, elocution, and pitch. Linguists have even given this speech pattern a name: sports announcer talk. Sociolinguist and dialectologist Valerie Fridland joins Host Flora Lichtman to break down the patterns and rules of this register. Guest: Dr. Valerie Fridland is a professor of linguistics at the University of Nevada, Reno, and author of “Why We Talk Funny: The Real Story Behind Our Accents.” Other episodes you may enjoy: The Art And Science Of Trash Talk What The Sigma Is Algospeak?
