it is not slajov zizek, but slavoj zizek.
its not pronounced slavoz but slavoy.
if the guy introducing slavoj actually used internet as he claims he did, he would have checked the number one google result for “slavoj zizek” search – his wikipedia entry – and his pronunciation might have been at least remotely close and not totally improvised.
google is stretching and improvising.
and they plan to make automated cars. :)
