Podfasters: people who listen to podcasts at speeds up to 300% of normalOn November 15, 2017 by Maybell
I remember the first time a blind friend let me listen in on her screen-reader’s text-to-speech narration, a high-speed chipmunk squeal that she had trained herself to decode; I was hugely impressed.
More than a decade later, I’ve found myself sometimes speeding up my favorite podcasts to 1.2 or 1.5 speed, especially when I have a big backlog to listen to, or when I discover a new podcast and want to get through its previous editions.
I’m not the only one, apparently — the “podfaster” phenomenon is composed of people who’ve learned to listen to podcasts at high speeds (even double- or triple-speed). It has some potential benefits besides speed — apparently higher tones are less likely to be masked by low-pitched street noises, HVAC or low-flying planes.
Neuroscientist Uri Hassan, whose Hassan Lab at Princeton studies brain responses to real-life events, has studied how the brain processes sped-up speech. He pointed out that even at normal speed, most people don’t catch every single word that’s being said. “If you make it one-third faster, it’s almost perfect — they don’t lose a lot,” he said. He also noted that the brain is able to easily adapt to different speaking speeds. “Your brain responses become slower when I speak slowly, and brain responses become faster when I speak faster.” But, he cautioned, comprehension starts to break down around 2x, and at 3x “it really breaks down.”
There’s one exception to this, though: blind people. “Because they are so used to only listening, they can speed it up faster than sighted people,” Hassan said. “They’re really trained.”

What does it mean to be a Republican “values voter?” Well, for sure, it means hating abortion and coming up with grotesque, rapey, lethal, cruel, absurd, unconstitutional (very, very unconstitutional), racist, regulations; tricking women into unwanted pregnancies; turning a blind eye to terrorism, and targeting vulnerable teens, while charging women with murder and defunding programs […]
