146.60 exabytes is about one-three-hundredth as much as All Spoken Words in Human History (recorded).
In other words, it's 0.0034 times the amount of All Spoken Words in Human History (recorded), and the amount of All Spoken Words in Human History (recorded) is 290 times that amount.
(2003 figures) (assumes 16 Khz, 16-bit mono recording)

For the purposes of his calculations, Liberman estimated the total duration of such a project to include 416,390,367 years of continuous audio.
