The read
By 2007, Cartwright had spent twenty years supplying the shriek, the cackle and the permanent adolescence of Bart Simpson — the kind of workload that grinds ordinary voices down. Fresh Air caught her speaking as herself, and the instrument found a machine in showroom condition: harmonic clarity optimal, pitch steadiness and volume steadiness optimal, register and chest resonance optimal, every pause the textbook length. She doesn’t idle much — the pause ratio runs below the band, brisk and forward-moving — but nothing in the signal shows wear. That’s not luck. A voice that survives two decades of professional yelling is a voice being looked after.
