Qfyilyi

general jurisdiction sessions. [5] Proponents of going
digital say that technology is the easiest way to get the
most accurate record of the proceedings, as the machine
records everything faithfully as it occurs and is not
[26] subject to human errors such as mishearing or
mistyping. [6] However, with the rise of high-quality
recording technology, reliance on court reporters 27 as a
record keeper is decreasing.

In the short excerpt above, the word following [26] will be subject or subjected. I think it should be subjected, but I am not really sure and can't convince myself why. Any help will be much appreciated.

You need the adjectival subject to here, because what you mean is “errors are liable to happen”.

You would only use the verbal subjected to to indicate that “as part of a systematic procedure, errors are deliberately introduced”.
