What is the "speak write" and "face crime" in 1984?

First
mentioned in Chapter Four of s novel of a futuristic dystopian society,
, a speakwrite is apparently some form of dictation system, in
which a user speaks into it and his or her words are displayed on a screen or, more probably
given the frequent association of paper to the speakwrite, the words on typed automatically onto
paper.  They are presented byas routine and oft-used pieces of office equipment.  Later in that
chapter, Orwells , , notes one of his coworkers busily engaged in using his speakwrite, although
under questionable circumstances:

Winston glanced across
the hall. In the corresponding cubicle on the other side a small, precise-looking, dark-chinned
man named Tillotson was working steadily away, with a folded newspaper on his knee and his mouth
very close to the mouthpiece of the speakwrite. He had the air of trying to keep what he was
saying a secret between himself and the telescreen.

Later, in Part Two, Chapter One, Winston is again using the speakwrite, this time in
the service of subversive actions:

. . .it was with
difficulty that he kept his voice from trembling as he murmured his figures into the speakwrite.
He rolled up the completed bundle of work and slid it into the pneumatic tube.

Given the period in which Orwell was writing €“
1984 was published in 1949 €“ it appears as though he his
speakwrite was modeled on the late-19th Century Dictaphone, in which one speaks into a tube,
very much like the speakwrite, and the words were recorded on a disc.

Facecrime, in contrast to the speakwrite, is not a thing, per se.  Rather, it is a
concept in which ones facial expressions, known to be a reflection of ones thoughts, can be a
violation of the law if those expressions are interpreted as subversive or disapproving of the
ruling regime.  In Chapter Five, Orwell describes facecrime as follows:

A nervous tic, an unconscious look of anxiety, a habit of
muttering to yourselfanything that carried with it the suggestion of abnormality, of having
something to hide. In any case, to wear an improper expression on your face (to look incredulous
when a victory was announced, for example) was itself a punishable offence. There was even a
word for it in Newspeak: FACECRIME, it was called.

In a
novel in which Thought Police play a prominent and particularly pernicious role, indicting an
individual on the basis of interpretations of that individuals facial expressions or nervous
tics is a part of the totalitarian nature of the society in Winston lives.
