Criticizing a 2002 estimate of 5,100 petabytes, linguist and University of Pennsylvania professor Mark Liberman asserted that it would actually require 44,000,000 petabytes 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.
