235 zettabytes is about five-and-a-half times as much as All Spoken Words in Human History (recorded).
In other words, the amount of All Spoken Words in Human History (recorded) is 0.180 times that amount.
(2003 figures) (assumes 16 Khz, 16-bit mono recording)
Criticizing a 2002 estimate of 0.0049 zettabytes, linguist and University of Pennsylvania professor Mark Liberman asserted that it would actually require 42 zettabytes to house a recording of all speech in human history, even at a relatively low level of quality. For the purposes of his calculations, Liberman estimated the total duration of such a project to include 416,390,367 years of continuous audio.
