I don't think this is true. Typically, the noise sources being used in hardware RNGs are very simple physical processes like shot noise. I think simulations of those are vastly simpler than simulations of human voices.
The circuit allegedly used in the Intel chip will produce a signal substantially more complex than that.
Indeed any noise circuit, even one based on shot noise or Johnson noise has numerous analog aspects that will alter the color of the noise, just as the human voice is more than just a vibrating vocal cord.
And this color will change from one chip to the next, will change with temperature, will change with overclocking. Where does the digital simulation get a true on chip clock to know that its overclocking is being changed on it?
